[BUGFIX] Use correct type in DB query

A database query was executed when creating a scheduler
task which fetched all optimizable tables.

This was executed with the wrong type in createNamedParameter
(string instead of string array) and resulted in exception in
some scenarios (with MySQL, with additional table mappings).

The problem is now fixed.
