Bug 28207: Fix biblio_framework.frameworktext isn't in GROUP BY

When a new framework is created and "Marc structure" is opened, a SQL
error happened if sql_strict_mode is on.

Test plan:
Create a 2 new biblio frameworks
Click "Marc structure" for one of them
=> You see the list of all frameworks with an existing structure
