This test checks to make sure that quotas are enforced per-origin instead of per-database, as they were prior to
The test clears all databases, sets the quota for the origin to 32k, then tries to insert 17k of data into two databases. If things go as planned, the UI Delegate will be informed of the exceeded quota and should increase the quota for this origin. Inserting 17k of data the third time should succeed again.
