Fix tap-google-analytics failing when end_date is provided in the config as null (None)
tap-google-analytics
fails when the end date is provided with a null value:
{
"key_file_location": "client_secrets.json",
"view_id": "...",
"reports": "",
"start_date": "2019-05-01T00:00:00Z",
"end_date": null
}
Update the tap to take into account that case also.
