obscache: skip the cache entirely if not up to date
The current update code has some race condition windows around updating. But we
also ensure the cache are up to date with every transaction. So outdated cache
mean another client have been mudding the repository but things will get back
in place at the next transaction.
So we just skip using the cache when not up to date. This is not the best we
could do. But this is good enough for now.

Testing obsolescence markers push: Cases D.3
============================================
Mercurial pushes obsolescences markers relevant to the "pushed-set", the set of
all changesets that requested to be "in sync" after the push (even if they are
already on both side).
This test belongs to a series of tests checking such set is properly computed
and applied. This does not tests "obsmarkers" discovery capabilities.
Category D: Partial Information Case
TestCase 3: missing prune target (prune not in "pushed set")
D.3 missing prune target (prune not in "pushed set")
====================================================
