Crash executing null AsyncRequest in IDB code.
<rdar://problem/18854856> and https://bugs.webkit.org/show_bug.cgi?id=144715
Reviewed by Darin Adler.
When UniqueIDBDatabase fails to execute an operation on the database work queue it usually
dispatches an AsyncRequest ID back to the main thread with an error callback.
For two of its operations it would then also dispatch the success callback.
In those cases the main thread would first take the AsyncRequest for the error callback out
of a map and then execute it.
It would then try to take the same AsyncRequest out of the map again, fail to do so, then
execute a null AsyncRequest.
This patch fixes the two functions to not dispatch both an error and success callback.
* DatabaseProcess/IndexedDB/UniqueIDBDatabase.cpp:
(WebKit::UniqueIDBDatabase::countInBackingStore): Return after dispatching the error callback.
(WebKit::UniqueIDBDatabase::deleteRangeInBackingStore): Ditto.
