Michael Wright 750a2d57bd Fix unnecessary_to_owned false positive 
Fixes #9351.

Note that this commit reworks that fix for #9317. The change
is to check that the type implements `AsRef<str>` before regarding
`to_string` as an equivalent of `to_owned`. This was suggested
by Jarcho in the #9317 issue comments.

The benefit of this is that it moves some complexity out of
`check_other_call_arg` and simplifies the module as a whole.
