[FIX] web: clear_uncommitted_changes on browser's back button

Browse Source 
This is done by guarding the `on_hashchange` evant handler with the
`clear_uncommitted_changes` function.

Note that the url has already changed when we are in this handler, so we
make sure to restore the old url when the user chose to continue its
edition.
