Pull request: errors: use `determineSpecificType` in more error messages

Before it would have say something like `Expected a … to be returned for the "…" from the function but got an instance of String.`, and with this PR it would say the more useful and more correct `Expected a … to be returned for the "…" from the function but got type string ('the input string')`.
