autodetect: demote candidate error to warning and plug fake{sink,src}

Browse source 
In the case where we have no suitable candidate we post a warning and plug a
fake-element. Do the same when non of the candidate work.

This is more consistent and plugin the fakesink as a fallback is probably
helpful for running unit tests without requiring hardware src/sink elements.

Fixes #722981
