Check transitive stream collision
    
    A transitive stream collision could happen in such a case, for example,
    modulea buildrequires foo:1 and bar:1, then foo:1 requires baz:1 and
    bar:1 requires baz:2, which will cause the collision on modules baz:1
    and baz:2.
    
    This patch checks the collision when submit a module build and each
    expanded (module stream expansion) module will be check. If a module has
    collision, error will be raised immediately.
