ui: disable revsetaliases in plain mode (BC)
ui.plain() is supposed to disable config options that change the UI to the
detriment of scripts. As the test demonstrates, revset aliases can actually
override builtin ones, just like command aliases. Therefore I believe this is a
bugfix and appropriate for stable.
