Subversion: Only fire changed when content has changed (#41036)

Browse source 
* Previously when checking out a subdirectory, if changes are made in the
repository that aren't present in the subdirectory (i.e. in a different
branch or similiar) then the changes handler still kicks in even though
the content of this working copy hasn't necessarily changed. Now we parse
the output of svn update and fire if anything changes at all.

* Should not be executable

* ==None doesn't do what I want, is None does
