/**
* This test is mainly to verify that persisted origins are not constrained by
* the group limit. It consits of these steps:
* - Set the limits as small as our limits allow. This does result in needing
* to perform 10 megs of writes which is a lot for a test but not horrible.
* - Create databases for 2 origins under the same group.
* - Have the foo2 origin use up the shared group quota.
* - Verify neither origin can write additional data (via a single byte write).
* - Do navigator.storage.persist() for that foo2 origin.
* - Verify that both origins can now write an additional byte. This
* demonstrates that:
* - foo2 no longer counts against the group limit at all since foo1 can
* write a byte.
* - foo2 is no longer constrained by the group limit itself.
