Follow-up from "Modify authority"

The following discussions from !773 (merged) should be addressed:

• @mzebrak started a discussion:

  I think all the methods where key can be passed could accept also clive PublicKey but that's a minor issue, lets do later or next MR

• @mzebrak started a discussion:

  as above

• @mzebrak started a discussion: (+4 comments)

  looks like we no longer need build and rebuild implemented and can just use compose and recompose like on f131dd90

  Its wip so apply it carefully (I see now I didn't renamed build_modify_working_account_authority_widget)

  Looks like similar thing may be probably done to authority_details.py but lets skip that to a different MR

• @mzebrak started a discussion:

  (in next MR) looks like we should abstract the filtering logic into the CliveCheckerboardTable so there will be no need to e.g call update_cell_colors during filtering.
