bzr-search increases HPSS count, causing tests to fail

[Jelmer Vernooij]

there are a bunch of tests in bzr core that check that a particular blackbox operation only takes X HPSS calls.

This breaks when bzr-search is installed because it sometimes hooks in to do extra operations, such as looking for a index on "bzr log", which causes these tests to fail.

We should probably just run these tests without any plugins installed.

Of interest, mailing list thread with discussion on what state hooks should be in during selftest:

I think we should enable hooks again by default, even in the test suite. Disabling or overriding particular plugins is now a lot easier than it used to be.

Let's take this to the mailing list, as part of the wider discussion about testing plugins better.
