Type resolve transformer: reorder tower scope

This commit prioritizes inner scopes above outer scopes
(before this commit, inner scopes had lowest priority).
NB: really it's not precise enough too,
because explicit importing scope should have higher priority
than inner scopes.
Also fixes problem with total Kotlin resolve test introduced
in previous commit.
