mobile: exit edit mode when navigating away from edit page

Navigating using the breadcrumb in the header did leave the
dive detail edit (and add) mode in such a way that (for example)
navigation in the dive list was suspended. Obviously, it is
debatable what should be done. Saving the edits/add, or
cancelling them. For now, this commit cancels them
silently. This is the exact same thing that is happening when
the user selects the dive list from the drawer menu.

Fixes: #932
