The ir.actions.todo record base.open_menu is used to redirect the user
to a menu after installing a module.
To do so, a new module override the record changing its action (toward a
menu) and setting its state to "open".
But with f7fe753 when one such changed action is removed after
uninstalling a module (or removing the action by any other way) the
base.open_menu would also be removed. Thus thereafter the open_menu will
not work anymore (since type "automatic" is lost).
With this commit, when whenever base.open_menu is removed, instead its
action will be replaced by base.action_client_base_menu which is the
original action.
