Travis: Initiating build for commit 'bc2f82d1c265ffa0dfc5f76bdadc6be68da5348f' on branch 'master': Fixes #6664, when replaying logs in log importer, use extra information present in Piwik URLs to determine visitor ID when distributing hits among recorders. If IP is not good enough indicator of visitor, this will increase accuracy of replayed logs.
