    User shouldn't remove their own roles on project

    Added a check if the user is trying to delete their
    own 'admin' role on the current project. This is added
    to prevent the users from locking their own
    access to Dashboard. Also, if the 'admin' role on the
    current project is removed, Dashboard automatically
    switches to another project for which the user has 'admin'
    role, but the previous project still is displayed as current.

    Fixes bug 1046538

    Also improved the unit test scenarios a bit.
