The ticket field specifications returned by `TicketSystem.get_ticket_fields()` is now cached.

That method used to be costly to call, and by calling it in `Query` constructor, we made Wiki pages containing lots of `[[TicketQuery]]` macros very expensive (#6436). There are probably several other situations that will benefit from this caching as well (like showing big roadmap pages, creating lots of `Ticket` instances, etc.).

Move `[ticket] restrict_owner` logic outside of the `TicketSystem.get_ticket_fields()`.
- this enables taking into account fine-grained permissions, for restricting the choice of possible owners even further if needed
- this makes it possible to have complete control over when the `get_ticket_fields` value will change, so we can cache it (related to #6436)

Code cosmetic fix, no CamelCase for variable names.

Btw, I'm not sure this code is still needed.

Fix typo affecting the values for the ''precision'' parameter for timeline requests (should have been ''minute'' and ''hour'' - no need for day as we anyway group entries by day).

Show completed date and time for the milestone ''completed'' information, on Milestone edit and view pages. Fixes #7648.

Edit new milestone with requested name, when such a milestone doesn't exist and the user has the MILESTONE_CREATE permission, instead of showing an error page.
