Title: [DO NOT MERGE] Removed unnecessary directories & tests

We are pulling all demo xblocks out into xblock-sdk, so that the xblock repo will only contain core xblock functionality.

Three tests were failing because they were testing a demo xblock's functionality specifically, instead of xblock itself.
