Invoice submission messages for Peru EDI now clearly indicate when documents are sent in testing mode. This helps users avoid confusing a test submission with a real submission to the government.

Before this commit, when you submit an invoice through the EDI even in testing mode, the message in the chatter is saying that the document has been sent to the government. Which is disturbing for the users, some of them think they submitted correctly the invoice but in fact it was in testing mode.

From now on, when the setting is set, the message is changed to say that you are
 in testing mode.
