Bug 898939 - Flip custom scope automation prefs for 449149-1{a,b}.html. r=bz

Bonus fix I noticed while working on this.

This was done before we flipped the default to make reftests always run with
dom.use_xbl_scopes_for_remote_xul=false (see reftest-cmdline.js). So to get
the full test coverage we're looking for here, we need to force the opposite
pref.
