Handle misencoding of login_source cfg in mssql (#16268) (#16275)

Browse source 
Backport #16268

Unfortunately due a bug in xorm (see https://gitea.com/xorm/xorm/pulls/1957) updating
loginsources on MSSQL causes them to become corrupted. (#16252)

Whilst waiting for the referenced PR to be merged and to handle the corrupted
loginsources correctly we need to add a wrapper to the `FromDB()` methods to look
for and ignore the misplaced BOMs that have been added.

Fix #16252
