    libecal: catch invalid CalObjModType values
    
    This protects backends without their own parameter checking
    from being invoked with invalid CalObjModType values. Note
    that this only excludes values that haven't been defined.
    Backends still need to check whether they support the
    selected mode.
    (cherry picked from commit e6eb665600248a28bccf268be70d5d3ffcdadb62)
