IndexedDBTransactionTest::Timeout now calls Timeout().

IndexedDBTransactionTest::Timeout now calls Timeout().

When the transaction timeout expires Timeout is called, which in turn calls
Abort(). Making the test a friend so that Timeout can be called makes this
a more realistic test. Also checking for correct diagnostic values.

This change didn't fix anything, it was just one of several new or enhanced
