Fixed #30023 -- Prevented SQLite schema alterations while foreign key checks are enabled.

2018-12-15T23:51:59Z

Prior to this change foreign key constraint references could be left pointing at tables dropped during operations simulating unsupported table alterations because of an unexpected failure to disable foreign key constraint checks. SQLite3 does not allow disabling such checks while in a transaction so they must be disabled beforehand. Thanks ezaquarii for the report and Carlton and Tim for the review.

Removed useless check in sqlite's DatabaseWrapper._savepoint_allowed().
