Allow empty string to clear URL-type DB fields. (#4780)

Browse source 
* Allow empty string to clear URL-type DB fields.

- To address difficulties with clearing URL-type fields like
  avatars, banners, site icons, this PR turns the URL type form
  fields into strings.
- This allows an empty string to be used as a "clear data", as
  in the case with the regular text form fields.
- Also includes various cleanups.
- Fixes #4777
- Context: #2287

* Fixing comment.

* Use Option<&str> and deref.
