filecache: create an entry in _filecache when __set__ is called for a missing one

Preserve the invariant that if P is a filecached property on X then
P in X.__dict__ => P in X._filecache.

Previously, it was possible for a filecached property to become out of sync
with the filesystem if it was set before getting it first, since the initial
filecacheentry was created in __get__.

Old behaviour:

  repo.prop = x
  repo.invalidate() # prop has no entry in _filecache, it's not removed
                    # from __dict__
  repo.prop         # returns x like before without checking with the
                    # filesystem

New:

  repo.prop = x     # an empty entry is created in _filecache
  repo.invalidate() # prop is removed from __dict__
  repo.prop         # recreates prop
