tests: remove initial bundle2 enabling in various bundle2 tests Bundle 2 is enable by default since 3.6 so we don't need this anymore.

convert: move svn config initializer out of the module level The svn_config_get_config config call was being called at the module level, but had the potential to throw permission denied errors if ~/.subversion/servers was not readable. This could happen in certain test environments where the user permissions were very particular. This prevented the remotenames extension from loading, since it imports convert's hg module, which imports convert's subversion module, which calls this. The config is only ever used from this one constructor, so let's just move it in to there.
