OTWO-3236 Fix SVN Failing Jobs (SlocJob)

* Recently when using svn 1.8.8 and encountering a new directory change
the expection wasn't handled and it was returning a non-zero exit code
* Earlier in 1.6.6, it was returning 0 as exit code and hence it wasn't occuring
* Now, the exception message has been updated matching the regex
