getUri() --> uri()

Using 5.4 here I had to change `getUri()` to `uri()` in `pragmarx/tracker/src/Data/RepositoryManager.php` to avoid an error. I assume it's triggered by the `log_routes = true` setting. On another note, tracker didn't work with a separate database (but that's perhaps my fault, and I didn't investigate further). Sorry for being not more precise.

Start in pragmarx/tracker/src/Data/RepositoryManager.php and inspect the getUri() call in the context of Laravel 5.4. Check whether the log_routes = true setting triggers the failure, and compare it with the reported uri() usage. Done means route logging no longer raises the reported error under Laravel 5.4.
