tweakdefaults: remove "bisect" from commands.status.skipstates...

tweakdefaults: remove "bisect" from commands.status.skipstates If you forget to clear bisect state after you're done bisecting (as I've done twice in the last week or so), the next time you run `hg bisect --good/--bad`, it's going to tell you "The first bad revision is:" etc. It's probably not obvious to new users what's going on, and having the verbose output about an ongoing bisection will probably help them, so let's turn it back on by default.
