[FIX] web: add support for TRUE_LEAF and FALSE_LEAF in ModelFieldSelector

before this commit, domain selector widget does not support
TRUE_LEAF and FALSE_LEAF i.e. [(1, '=', 1)] and [(0, '=', 1)] respectively,
the reason is the chain part of the domain i.e. field name has value 1/0 and
we don't have field name like 1 and 0 in domain and hence ModelFieldSelector
don't accept it

after this commit, domain selector can handle this special two domains which is
[(1, '=', 1)] and [(0, '=', 1)], add support for chain with 1/0 in ModelFieldSelector
