* Fix recovery for unsaved background tabs (#2884)
* Recovery: scheduled autosaves of every tab write on the worker thread (#2884)
After #3139, Autosaver::save waits for the write and Autosaver::tick runs
it on a worker. The scheduled path now goes through tick (which skips a
tab whose previous write is still running), so several dirty tabs no
longer write on the window thread each interval (#3044). save stays for
Save, close and shutdown. Each tab's autosaver has no clock of its own:
the shared cadence decides when it is due. The tests wait for the
writes a tick started.

* Recovery: closing a tab waits for its running autosave before removing the entry (#2884)
With the autosave on a worker thread, discard could remove the files and
the lock while a write was still running; the write then recreated the
entry without a lock, and the next launch offered a design closed with
Don't Save. discard now ends the running write first, as Drop does.
