When calling the REST API testmanagement_campaigns/:id/testmanagement_executions, sometimes the definition.all_requirements is not an array but an object.

This is due to the fact that array_filter (which is used to remove requirements artifacts that user cannot read) do not change array keys:

Array keys are preserved, and may result in gaps if the array was indexed. The result array can be reindexed using the array_values() function.

When it is the case, then the json returned is not an array but an object with the numeric index of the associative array being the object index:

    ...
    "all_requirements": {
        "12": {
          "id": 11226,
          "uri": "artifacts/11226",
          ...

While the expected json would be:

    ...
    "all_requirements": [
        {
          "id": 11226,
          "uri": "artifacts/11226",
          ...
