Follow-up fix after qa for bug#9916.
Merge branch 'master' of git.otrs.com:otrs/otrs
Fixed web installer issue w/Named Instances

the ,1433 port number that was appended in the Installer caused
problems with named instances such as localhost\SQLExpress or
localhost\Production.

Besides, the port number 1433 is assumed standard, so it is not even
needed in the connection string.
Code cleanup.
