Bug 36618: Make biblio creation optional for ERM local titles

This patch makes biblio creation on local title creation optional.

Test plan:
1) Navigate to the local title creation form
2) Create a title and leave the "Create record" box unchecked
3) Submit the form
4) Search the catalogue for the title you have just created - no biblio result will be available
5) Repeat steps 2 - 3 but this time check the box to create a record
6) You should now be able to find a record in the catalogue for the title you just imported
