Fix My link missing repository_url for app pages

The "m" shortcut to create My Home Assistant links was not including the
repository_url parameter for app pages. Two issues fixed:
1. optional_params from redirect config were never processed in _createMyLink
2. ha-config-app-dashboard was stripping repository_url from the URL on load
