Get location info from spec

There are cases when spec location info points to core, not to the student's file. I am not sure what causes it. So far I just changed the expected location info in student_test.clj to make the tests pass, but this is obviously not ideal.

The spec location info points to clojure.core when the function is overwritten and uses 'apply' in the overwritten function. There may be other cases. For instance, we need to look into cases like secondary errors.

Let's postpone secondary errors for now: I suspect/hope this may be changing in a newer version.
