Speculative checkin (requires approval of Gerhard Haering)

This backs out the test changes in 46962 which prevented crashes
by not running the tests via a version check.  All the version checks
added in that rev were removed from the tests.

Code was added to the error handler in connection.c that seems
to work with older versions of sqlite including 3.1.3.
