Resolving incorrectly fails with AmbiguousColumn

[lukas-mi]

Hi, seems like resolver gets confused about the context used for resolution when trying to resolve columns in nested queries and fails with AmbiguousColumn error, e.g.: select a from demo.foo where a in (select a from demo.foo);

Hey, not sure if you managed to find a fix for this. Right now, none of the original authors (myself included) are active on this project, but if you're able to get a fix going I can review a PR.
