Fix for Bug 6458 - incorrect parsing result in translation processing

Fix for Bug 6458 - incorrect parsing result in translation processing

There is template logic in manage-marc-import.tt which is intended
to set the "selected" option for the framework chooser ("Add new
bibliographic records into this framework"). However, I can't see
any place in the code which sends the "selected" variable to the
template, and I can't see any circumstance in which a value would
be passed to the template.

This patch removes the "selected" variable from the template.
