Fix management of mRunScheduled state in reporting engine.

[bzbarsky-apple]

Without this change, we can schedule a reporting run, then do a sync
Run (due to urgent events), then (unnecessarily) schedule another
reporting run.

Problem

See above.

Change overview

Make sure to unset our "run scheduled" boolean only when we actually call the async callback.

Testing

Verified that this fixes the test from #20692 on the SHA where that test crashes.
