CADC int tests failing

[andamian]

3 cadc int tests are failing.

2 of them (test_get_images, test_get_images_async) fail with a VOTable parse error which can be caused either by service or VOTable incompatibilities with the spec. It requires further investigation.

warning = E02('?:?:?: E02: Incorrect number of elements in array. Expected multiple of 2, got 1')
config = {'_warning_counts': {<class 'astropy.io.votable.exceptions.E02'>: 1}}
stacklevel = 3

    def _suppressed_warning(warning, config, stacklevel=2):
        warning_class = type(warning)
        config.setdefault('_warning_counts', dict()).setdefault(warning_class, 0)
        config['_warning_counts'][warning_class] += 1
        message_count = config['_warning_counts'][warning_class]
        if message_count <= conf.max_warnings:
            if message_count == conf.max_warnings:
                warning.formatted_message += \
                    ' (suppressing further warnings of this type...)'
>           warn(warning, stacklevel=stacklevel+1)
E           astropy.io.votable.exceptions.E02: ?:?:?: E02: Incorrect number of elements in array. Expected multiple of 2, got 1

The third one (test_list_jobs) is failing in PyVO with an unexpected element. Again incompatibilities with the spec in either the service or PyVO - to be investigated.

>           warn(warning, stacklevel=stacklevel+1)
E           pyvo.utils.xml.exceptions.UnknownElementWarning: None:2:0: UnknownElementWarning: Unknown element jobs

This is a duplicate of #2242 so I'm closing it to keep it tracked there and in #2203
