Error parsing `get_api_test_result` data

[Trond Hindenes]

Describe the bug
When checking the status of a synthetics test, I'm getting the following error (if the test has completed and failed):

datadog_api_client.exceptions.ApiTypeError: Invalid type for variable 'date'. Required value type is dict and passed type was str at ['received_data']['result']['response_headers']['date']

To Reproduce
this only happens if the configured test has completed and the test failed, for example if the api returns a 500 while the test assertion required a 200 status.

Expected behavior
the call should not fail

Screenshots

Environment and Versions (please complete the following information):
datadog-api-client==1.12 on python 3.9
