The ungroupedlist api parameter will be deprecated from the wbgetentities and wbgetclaims modules on Wikidata as of the next deployment on Wednesday 29th July.

The parameter has very low usage and removing it removes code complexity in the API.

Removal change - https://gerrit.wikimedia.org/r/226643

To adjust for this change users of the API simply have to use the default format, which is grouped by property ID.
