rebase: remove bailifchanged check from pullrebase (BC)

This saves us a relatively superfluous status check for pull --rebase (if
rebase runs, it'll check for a clean working directory anyway), and brings hg
pull --rebase closer to hg pull && hg rebase.

This is a behavior change because pull --rebase with a dirty working directory
will now abort after performing the pull rather than before.
