Ensure ui pattern field group form hooks run last

[swim]

The field group module reorders form alter hooks to make theirs run last. The ui pattern field group module adds a submit handler to the front of the submit array but for this to work as expected the field_group form alter needs to run before. This patch ensures the ui pattern field group form alters run after field_group, setting the correct submit handler order.
