Bug 22878: Do not pass layout_id on creating a layout

Attempting to create a patron card layout with mysql strict mode on gives the following error:
  DBD::mysql::st execute failed: Incorrect integer value: '' for column 'layout_id' at row 1

Test plan:
- Turn on sql_strict_modes
- Create a new patron card
=> Must success with this patch applied
