Bug 23844: Check if field defined in framework and specify 'Default' for framework

To test:
1 - Go to Cataloguing
2 - New from Z3950
3 - Find an import a record
4 - Check the plack logs:
Use of uninitialized value in string ne at /kohadevbox/koha/cataloguing/addbiblio.pl line 565.
Use of uninitialized value in string ne at /kohadevbox/koha/cataloguing/addbiblio.pl line 580.
Use of uninitialized value $frameworkcode in string eq at /kohadevbox/koha/cataloguing/addbiblio.pl line 711.
Use of uninitialized value $frameworkcode in string eq at /kohadevbox/koha/cataloguing/addbiblio.pl line 715.
Use of uninitialized value $frameworkcode in string eq at /kohadevbox/koha/cataloguing/addbiblio.pl line 734.
5 - Apply patch
6 - Repeat
7 - No new errors
8 - Confirm selecting 'Default' from 'New from Z3950' dropdown also generates no errors
