- stop using a `switch()` statement in favor of some `if/else` ones to avoid a possible notice error when getting all allowed BP Attachements.
- stop using `wp_match_mime_types()` inside the `bp_attachments_get_allowed_mimes()` function. Using `wp_match_mime_types()` was generating unconsistent results when trying to get all BP Attachments allowed mime types.
