background: don't tank if background is destroyed before it gets a pipeline

Browse Source 
Right now we call unset_texture from MetaBackground's dispose method.

unset_texture assumes there's a pipeline available, but there may not
be if the object was just created.

This commit fixes that incorrect assumption.
