xProfile: fix regression in wp-admin field types screen where duplicate field templates were being shown for pre-2.0 custom field types.

A switch statement in the original `xprofile_admin_field()` was mis-read and an action was being triggered when it shouldn't have, causing the field templates to double up.
Fixes backwards compatibility with existing plugins that add custom field types.

Don't do a strict type check when deciding on bp_activity_add_user_favorite() return value

Since r8132, bp_activity_update_meta() has returned an integer value when
falling through to add_metadata(). Thus, we should have a more generous test
for whether the update has been successful. See #5399
