exceptions not propagated up from all v3 API extension points

[Christopher Yeoh]

Some extension points for the V3 API are supressing rather than propagating exceptions from plugins because the extension manager is not passed the propagate_map_exceptions parameter.

    Fix V3 API server extension point exception propagation

    Adds the propagate_map_exception parameter to extension
    manager initialisation in the servers plugin so extension
    points for the V3 API propagate exceptions rather than
    supress them. The parameter was missing from some of the
    extension point managers.

    Also adds a missing V3 API personality test which exposed
    the problem with exceptions not being correctly propagated.

    Very minor spelling fix to one of the tests
