This will change the hash of the URL when a new tab
gets selected. Vice versa when the billing page is opened
the appropriate tab is selected according to hash of
the URL. This means when the card gets updated the
page would be reloaded correctly to show #payment-method
tab.
The actual implementation of the change will be a cron job that runs once a
day and generates invoices for anyone with an account_balance > 0.
There are currently no tests for that part of the flow, so no tests had to
change.
