MINOR: backend: search conn in idle/safe trees after available
If no matching connection is found on available, check on idle/safe
trees for a matching one. This is needed because now idle connections
can be differentiated from each other.
If only the available list was checked because not empty, but did not
contain a matching connection, we could miss matching entries in idle or
safe trees.
