This reverts commit 37d158f1.

Fix undefined method getProjectsAuthorizedForUser.

to check was hardcoded.

When a user don't have the permission
`$user->rights->projet->all->lire`, viewing some tasks related entities
(like `tasks/contact.php?id=1&withproject=1`) cause `Call to undefined
method Task::getProjectsAuthorizedForUser()` fatal error.

The problem is caused by calling getProjectsAuthorizedForUser on $object
insted of $projectstatic.
