consolidate_rares method only treats the first unconsolidated rare item

**Botty Version**
Master branch, latest commit from aeon0 (https://github.com/Ricola3D/botty/commit/22ab86b3877e441a61cfb46f43bf5b368d8251cf).

**Describe the bug**
There is a return is the algorithm instead of a continue, making it skip other unconsolidated rare items. Other consolidate methods seem to have the same issue.
