don't cache parses twice

Before this commit, `Parse`s for original file ended up two times in
salsa's db: first, when we parse original file, and second, when we
parse macro or a file.

Given that parse trees are the worst ofenders in terms of memory, it
makes sense to make sure we store them only once.
