rHGfbe34945220d: context: set repo property in basectx
Summary

It seems like a good practice to call the super constructor. Let's
start by passing the repo along to basectx so it can assign it to a
private attribute. We should perhaps pass the rev and node along as
well, but that requires more work before it can be done.
