## [FIX] timesheet_grid: remove duplicate rpc call

Before this commit, the `loadTimesheets` method is called 2 times in a
row, that method does a rpc call to load the existing timesheets and so,
it is not needed to call it 2 times since the rpc will return the exact
same result.

This commit removes the rpc call when we compute the suggestions to only
load the timesheets when we load all the data.

## [FIX] timesheet_grid: show chronological view instead of project view

Before this commit, the `by project` view were loaded first in the
timesheet assistant action, to group the suggestion by project, the
problem is at the beginning the view will not really show a perfect
matching and so the user could think the feature does not work and he
will not understand how to correctly match the suggestions shown in the
view.

This commit changes the view loaded by default in Timesheets Assistant
to first show the chronological view, that view is more logical for the
current user to rethink what he did in the past to correctly map the
events to a project and a task when he generates his timesheets thanks
to those events. The by project view is still useful afterwards when the
system has learned the choices made by the current user.

## [FIX] timesheet_grid: ensure events are consumed forever

Before this commit, the suggestions removed by the current user comes
back when he changes the date and come back to the day he removes the
suggestions. The reason is because a shallow copy of events consumed is
made and that copy alters the duration of the initial object.

This commit avoids copying the consumed events object to make sure the
initial object is not altered when processing the events to remove them
if they are removed before by the user.

### Steps to reproduce the issue:

1. install timesheet_grid and Activity watch, makes sure Activity watch
collects some activities on your computer.
2. Go to Assistant menu in timesheets app.
3. Remove some suggestions displayed in the right panel.
4. Go to next date.
5. Come back to previous date.

### Expected Behavior:


The suggestions removed should not appear again.

### Actual Behavior:

The suggestions removed come back in the view.

## [FIX] timesheet_grid: fix flicker when suggestion selected

Before this commit, when the user selects a suggestion in timesheet
assistant, there is a small flicker appears because the height of the
row grows because of the border added to highlight the suggestion
selected.

This commit reviews a bit the style to make sure the border bottom in
the previous element is removed if the element is not selected or if the
2 consecutives suggestions are selected.

## [FIX] timesheet_grid: fix discord rules to handle discord in web

Before this commit, when the user uses discord in its browser instead of
the app on his computer, the discord rules don't catch the activity
watch events because the tab title is different than the windows name in
the app.

This commit adapts the regex of Discord rules to handle the both use
cases.
