Fix double-click when deleting a bill (#349) (#372)

When double-clicking on the delete button, the first click actually
deletes the bill, and the second click does the same action again. But
as the bill is already deleted, it displays a 404 page which can be
misleading.

This fix makes the app trigger a redirect when the bill seem to doesn't
exist, fixing this strange behaviour.
