ASSERTION FAILED: !m_backingStore in WebCore::IDBServer::UniqueIDBDatabase::didDeleteBackingStore(uint64_t)
https://bugs.webkit.org/show_bug.cgi?id=197741
<rdar://problem/50625006>

Reviewed by Youenn Fablet.

If an open request is made before a delete request, open task should be performed before delete task on the
database thread. After r242911, open request needs to wait decision of StorageQuotaManager before posting task
to database thread, while delete request needs not. This makes deletion happen before open.

We need to make sure tasks are in correct order by not starting next open or delete request when database is in
the middle of open or deletion.
