Fix race condition in dispatch.go (#3826)
* Fix race condition in dispatch.go

This commit fixes a race condition in dispatch.go that would cause
a firing alert to be deleted from the aggregation group when instead
it should have been flushed.

The root cause is a race condition that can occur when dispatch.go
deletes resolved alerts from the aggregation group following a
successful notification. If a firing alert with the same
fingerprint is added back to the aggregation group at the same time
then the firing alert can be deleted.

Simon Pasquier 4535311c34 dispatch: don't garbage-collect alerts from store
The aggregation group is already responsible for removing the resolved
alerts. Running the garbage collection in parallel introduces a race and
eventually resolved notifications may be dropped.
