With xfaces 3.3, facedb search will perform incorrectly under certain
circumstances.  Found faces are cached under only the filename they were
found under within a given database and not under the database+filename.
This patch does not address this caching problem, but simply extracts
the cache check code in the face search as a quick & dirty workaround
that may well introduce new bugs.

See patch-graaff for an alternative patch for this problem.
