MINOR: backend: search conn in idle tree after safe on always reuse

Browse Source 
With http-reuse always, if no matching safe connection is found, check
in idle tree for a matching one. This is needed because now idle
connections can be differentiated from each other.

If only the safe tree was checked because not empty, but did not contain
a matching connection, we could miss matching entry in idle tree.
