Solved a few problems of auto by bypassing the call to apply. Indeed, calling apply was inefficient (doing again a unification known to work) and moreover unsound (apply's unification is poorly tunable and the flags used in the first unification - in clenv_unique_resolve - were lost for apply). Solved the problem of still having a pretty acceptable user-friendly "info auto" by concealing the direct call to "clenv_refine" as a call to apply.
