Products.meetingcommunes

------------------

- Fix template_path not used for some templates in `example_fr` profile.
This prevented install from profiles located in other packages.
[aduchene]
- Removed translations for advice WFA
`meetingadvicefinances_controller_propose_to_manager` as it does not exist anymore.
[gbastien]
- Fixed POD templates `deliberation.odt` and `deliberation_recto_verso.odt`,
`MeetingItem.getCertifiedSignatures` is no more an adaptable method
(removed `.adapted()`).
[gbastien]

------------------

- Import `get_person_from_userid` from `collective.contact.plonegroup.utils`
instead `Products.PloneMeeting.utils`.
[gbastien]

---------------------

- Added parameter `ignore_not_given_advice=False` to
`CustomMeetingItem.showFinanceAdviceTemplate`, when `True`, this will hide
the POD template when advice is `not_given` or `asked_again`.
[gbastien]

--------------------

- Added `test_pm_Show_advice_on_final_wf_transition_when_item_in_advice_not_giveable_state`
that will test that when item is set to a state in which advice is no more
editable, `advice.advice_hide_during_redaction` is not set back to `True`
if advice was not in it's workflow final state (when using advice custom workflow).
[gbastien]
- Adapted `test_Get_advice_given_by` to check that `get_advice_given_on` is
the advice WF `signFinancialAdvice` transition date when using a custom WF.
[gbastien]

--------------------

- Adapted code to use `imio.helpers.content.richtextval` instead `RichTextValue` when possible.
[gbastien]

--------------------

- Added translations for the `add_advicecreated_state` WFA.
[gbastien]
- Every item related search (Collection) use `sort_on` `modified` instead `created`.
