tor: Change auth order to only use HASHEDPASSWORD if -torpassword

Browse source 
Change authentication order to make it more clear (see #7700).

- If the `-torpassword` option is provided, force use of
  `HASHEDPASSWORD` auth.

- Give error message if `-torpassword` provided, but
  `HASHEDPASSWORD` auth is not available.

- Give error message if only `HASHEDPASSWORD` available, but
  `-torpassword` not given.
