Fix scaladoc of Try#failed

The documentation stated that it returns a Success[Throwable] regardless, either containing the failure or an UnsupportedOperationException. However only Failure#failed returns a success; Success#failed returns a Failure.

Also the phrasing of "Completes this `Try`" and "that `Try` failed with" sounds like it was copy-pasted from Future? Trys don't complete, nor fail, they are immutable.
