Retry visiting URL if not successful

A test failed because it tried to perform an action before the page
had loaded. This shouldn't happen - the test shouldn't proceed until
navigation is complete.

This change adds logging to confirm that it attempted to visit the
given page, and it retries if navigation isn't successful.
