Bug 6415: Can't make patron card batch

TT corrections from bug 6343 for label creator were also needed for patron card creator.

- Manage Batch and New Batch were missing the branch info
- Add link on patron search was missing batch id parameter

To test:
- Check branch is correctly shown on pages 'Manage Batch' and 'New Batch'
- Check you can create a new batch and add names to it by using the 'Add'
right to the patron's name
