Fix circular symlinks when update pre-usr-merge

I posted about a circular symlink getting created when update Easy 5.4.10 to 5.5, and the .session folder got converted to usr-merge folder hierarchy:

This can happen in other places, so I have put in some code that finds all circular symlinks and deletes them:

So, looks like another release not to far off.
