evolve: don't show working directory obsolete message if we were on it

This patch tweaks showing wc obsolete message functionality to not show the
message if the operation led us to the same changeset we were on before and it
didn't obsoleted it. This make failed updates, update on current changeset and a
pull with no change omit showing the message.

This has some cons like if you are on rev 1 which is obsolete and you do `hg up
<revset>` where revset is some revset which resolves to the rev 1, we won't show
the warning as shown earlier.

This test file test the various messages when accessing obsolete
revisions.
