#21 Menu item checks stay visible for views failures

[Muriel Salvan]

In the views menu, when we are trying to instantiate a view on a missing Tag, the check next to the menu item does not disappear.

Steps to reproduce:
1- Create a new Tag
2- Create a new view on this Tag
3- Delete the Tag (the view will disappear)
4- Activate the view from the Views menu: an error occurs, normal
5- Check the menu: the check should have disappeared.

It is needed to force an update on the menu item in case of failure, as the menu item automatically adds itself the check.
