[BUGFIX] Always load label for edit notification

If a record is edited via single field mode (aka "columnsOnly"), the
label field as defined via TCA may be missing, rendering "[No title]" in
the notification message.

Before compiling the notification message, it is now checked whether the
label exists already. If not, the label of the record is fetched from
the database, if such label field is configured via TCA at all.
