[FIX] website_event_meet, *: properly await edit option before reload

*: website_sale

This is a follow-up of [1], which missed some occurrence of the same
issue that it fixed.

E.g.
- Add a delay to the "write" of the event model
- Go to /event/<event_id>/community
- Enter edit mode
- Click on the page
- Enable the room creation option
=> The page reloads but nothing seems to have been done... it is
   actually *being* done: the page reloaded too soon.

Note: this commit also marks some other occurrences which are not buggy
but might be in the future if not properly changed. To be adapted in the
master forward-port.
