Hide output about SVN::Core not being found during tests.

If the user doesn't have SVN::Core installed or working then the SVN tests properly turn themselves off. But the user doesn't need to know that SVN::Core isn't loadable as a Perl module. Unless of course they are trying to debug the test, so lets relegate the Perl failures to --verbose only.
