    Fix marshalling of GByteArrays
    
    In _pygi_marshal_from_py_array(), set the array length after copying the data
    in the GI_TYPE_TAG_UINT8 case (which applies for GByteArrays), otherwise it
    will always come out as zero length.
    
    Enable the TestGByteArray.test_bytearray_none_in() test case as that works now.
