**Current behavior:**
Creating a fixed tax with the edi formats ubl_bis3 and nlcius_1
then creating an invoice with this tax tied to a product will
cause a traceback when a user tries to confirm the invoice.

**Expected behavior:**
The invoice will post as any other might.

**Steps to reproduce:**
1. Create a NL company with l10n_nl_edi accounting

2. Create a tax with the following field values:
     *tax computation: fixed*
     *affect base of subsequent taxes: True*
     *base affected by previous taxes: True*

3. In the customer invoices journal for the created company,
     go to the 'Advanced Settings' notebook tab and enable the
     NLCIUS and Peppol options under 'Electronic Invoicing'

4. Create a new invoice with some product and attach the newly
     created tax to it, then try to confirm the invoice to see
     the traceback

**Cause of the issue:**
The edi format tags invoke different instances of the
get_invoice_line_allowance_vals_list() method. This method
returns a dict list where the dicts only sometimes contain the
key 'allowance_charge_reason_code'. A subsequent expression
expects this key in the dict which can cause a KeyError.

**Fix:**
Check instead for a 'charge_indicator' key, which is present in
both the ubl_bis3 and nlcius_1 val dicts, allowing the correct
total to be summed and reflected in the EDI document output.

Currently, the `plan_id` used to create analytic accounts is not the one set in the settings.

Steps to reproduce:
-------------------
* Go to the **Settings**
* Enable developper mode
* Select **User & Companies** > **Groups**
* Select `Technical/Analytic Accounting`
* Add user
* Go to the **Project** app
* Select **Configuration** > **Settings**
* Under **Time Management**, enable Timesheets
* Under **Analytics** > **Analytic Plan**, select Projects
* Create a new project
* Go into the settings of the project
* Under the **Settings** tab, select the internal link for the **Analytic Account**
  > **Observation**: The Plan is set to Projects
* Go to **Conffiguration** > **Settings**
* Under **Analytics** > **Analytic Plan**, change Projects to Departments
* Create a new project
* Go into the settings of the project
* Under the **Settings** tab, select the internal link for the **Analytic Account**
  > **Observation**: The Plan is still set to Projects

Why the fix:
------------
When creating, an analytic account, the plan is computed with `_get_all_plans()`. https://github.com/odoo/odoo/blob/e365e22485dc45f1cbe87ae93395b022a4724a3c/addons/project/models/project_project.py#L894-L903

Inside `__get_all_plans()` the plan is computed as follows: https://github.com/odoo/odoo/blob/e365e22485dc45f1cbe87ae93395b022a4724a3c/addons/analytic/models/analytic_plan.py#L106-L107

However, the setting that the user changes in the frontend corresponds to `analytic.analytic_plan_projects`. https://github.com/odoo/odoo/blob/e365e22485dc45f1cbe87ae93395b022a4724a3c/addons/project/models/res_config_settings.py#L18-L22

This seeting is not company-related. It can be used on projects even if they have a `company_id` set to false. We fallback on `_get_all_plans()` if the user did not specifically choose a plan in the settings.
