throw NoSuchFeaturesException if no data available for extents (CARD4L)

[bossie]

org.openeo.geotrellissentinelhub.BatchProcessingService will throw a NoSuchFeaturesException in case the SHub catalog returns no hits for the specified extents, at least in the non-CARD4L case. This needs to be done for CARD4L too. There's already a test that could use a better name in the form of org.openeo.geotrellissentinelhub.BatchProcessingServiceTest#startCard4LBatchProcessesForXXX.

Don't forget to translate it to an appropriate error code (Open-EO/openeo-geopyspark-driver#224)

This problem manifested itself recently (j-7f841b9888c247929df5f69bfb053c6d) as a misleading error in the async_task handler:

failed to handle polling batch processes for batch job j-7f841b9888c247929df5f69bfb053c6d:

Earlier logs:

saved newly scheduled CARD4L batch processes [] for near future use (key ('SENTINEL1_GRD', (3.6675152618923206, 50.763255632654214, 3.838210383127976, 50.903414110950855), 'EPSG:4326', '2014-11-18T00:00:00+00:00', '2014-12-31T00:00:00+00:00', ('VV', 'dataMask', 'localIncidenceAngle'), 'COPERNICUS_30', (('sar:instrument_mode', (('eq', 'IW'),)), ('sat:orbit_state', (('eq', 'ASCENDING'),)))))

Indeed, the list of batch request IDs in the job's dependencies is empty:

[
  {
    "collection_id": "SENTINEL1_GRD",
    "batch_request_ids": [],
    "results_location": "s3://openeo-sentinelhub/10226947-dda5-416c-9d7d-e0aaead7cce2",
    "card4l": true
  }
]

An empty list is falsy, resulting in the KeyError. This can be averted by throwing a NoSuchFeaturesException earlier.
