    sessionMode: Drop allowExtensions property
    
    Now that we allow extensions at the lock screens, extensions
    are allowed for every session mode gnome-shell would typically
    change to at runtime.
    
    This means there's little advantage to having an allowExtensions
    property in the session mode definition.
    
    This commit simplifies the code a bit by dropping the property.
    
    Third party session modes can still lock down extensions through
    gsettings if they need to.
