Change the journal_mode pragma so that it always returns the current journal mode, even on a failed attempt to change the journal mode. Allow the journal mode to be changed as long as there is not a pending transaction. Ticket #3811. (CVS 6526) check-in: 419e320a user: drh tags: trunk

#
# Verify that journal_mode=OFF works as long as it occurs before the first
# transaction, even if locking_mode=EXCLUSIVE is enabled.  The behavior if
# journal_mode is changed after the first transaction is undefined and hence
# untested.
