Make clients wait to refresh bridges when they have a recent descriptor

But when clients are just starting, make them try each bridge a few times
before giving up on it.

These changes make the bridge download schedules more explicit: before
17750, they relied on undocumented behaviour and specific schedule
entries. (And between 17750 and this fix, they were broken.)

Fixes 23347, not in any released version of tor.
