When I rewrote com_fields to use groups instead of categories, I just copy-pasted the alias field. But it is in fact not used anywhere and thus can be removed.
Summary of Changes
This PR removes all traces to an alias in fields groups
Testing Instructions
Delete the alias column from your database table #__fields_groups
Check that creating/editing/saving/deleting field groups still works
