The original code replaced sys.path[0] which is ''
(aka the current directory).  It's a little odd to
rely on the 0th element being something that is safe
to remove.

By prepending the path we have the same intended effect without
having to know that the 0th element is something that is
safe to remove.

Does removing '' break relative imports? (It might...)

Due to the portability concerns with relative imports the
recommendation is to always use absolute imports.  Thus, this
shouldn't hurt us in practice if we stick to absolute imports,
but I figured I'd mention it as another reason why prepending
might be preferred over replacing.
