[roll] Roll cobalt [cobalt] Avoid deadlock on DO_NOT_COLLECT

On deletion, Cobalt gets stuck for 10 minutes until the timeout in
WaitUntilSave gets triggered. The deadlock occurs because initial-thread
is holding a lock on data_mutex_ so no new calls to GetMetricAggregate
will return until after the deletion is written to disk, but
writeback_thread_ also wants to lock data_mutex_ when it saves the
changes to disk.

There's no reason inital-thread needs to wait for the save to disk, so
we can get rid of this problem by not calling WaitUntilSave.

Original-Fixed: b/314009944
Tested: Set policy to DO_NOT_COLLECT on smart display, deadlock not seen
Tested: `./cobaltb.py test`
