Make query text and file commands consistent

We were using two different implementations for opening the query file
and query text between the query history and the results view. This
moves the better implementation in the view to a command and uses these
commands for opening the query text/file in the query history and view.
This results in consistent error messages and behaviour between the two
different views.
