(fix) MSSQLSERVER case insensitive for conn string

 - A user can specify 'mssqlserver' in a manifest, which in turn writes
   that config to disk for later use.  When doing the comparison when
   building a connection string, MSSQLSERVER should always be left off.
   Previously, the insensitive match would caused non-working connection
   strings to be built.
