Fix [clenv_missing] to compute a better approximation of missing
dependent arguments. It breaks compatibility as some [apply with]
clauses are not necessary anymore. Typically when applying [f_equal],
the domain type of the function can be infered even if it does not
appear directly in the conclusion of the goal. Fixes bug #2154.
