elm: Fix some ERR messages following previous patch

This simply avoids calling functions on NULL objects, since
the previous patch would ERR out rather than silently ignore
the problem.

I just add explicit NULL checks before calling the functions,
so it's clear the object could be NULL (in the widget).
