Summary

This commit fixes the last test failures when using the simple
store extension!

It turns out that hg manifest --all locks the repo and scans for
revlogs. This feature was added by 71938479eff9 in 2011. I am
debating changing the behavior. But that can occur in another
commit.

As part of debugging this, I realized that test-manifest.t is the
only meaningful tester of hg manifest --all and that test was
improperly disabled when bundlerepos aren't supported. The test is
testing manifest behavior, not whether you can hg pull from a
bundle. So I changed the test to hg unbundle instead.

FWIW, I wasted a non-trivial amount of time tracking down this
failure. I thought the issue involved Git, which is why I refactored
the test to be more deterministic. Never in my mind would I have
guessed that code in hg manifest would scan revlogs. I should have
looked there to begin with. Doh.
