* Require profile fields to belong to a group
Remove the empty group dropdown from the group select tag
Remove the optional: true from the belongs_to validation (raise a
validation error on save if the group is not provided)
Update test to remove belongs_to's optional setting
* Update ProfileFields::Add spec to include profile field group
* update factory to ensure a non-empty profile field group
* Add required profile field group to seeded profile fields
Since profile field is required, create was failing (silently).
Add required field so these are available in e2e tests.
* Use factory `association` to create a profile field group
https://github.com/thoughtbot/factory_bot/blob/master/GETTING_STARTED.md#explicit-definition
* provide required profile field group when posting data
* Fix one spec, drop another
Both of these scripts will be removed in the other branch (changing
the attribute name) - dropping the test here seems lower trouble than
modifying an out of data data update script to pass.
* skip test slated for removal
Similar to the last commit - this test exercises a script about to be
archived in the other branch.
