Bug 32399: Remove FK constraints while changing columns

Bug 32399: Remove FK constraints while changing columns

Some users have reported that the dbrev of bug 30483 fails. This might
depend on bad data, SQL server version, etc.
We now remove the constraints temporarily.

Test plan:
Reset your version in order to pass this dbrev again. So below
22.06.00.041.
* update systempreferences set value='22.0600040' where variable = 'Version';
Run updatedatabase.

Bonus: Create an issues record with invalid itemnumber (set FK check
off when doing so). Verify that dbrev fails and installer stops.
