Should error more gracefully/clearly when getting a 403

[thomasjthomasj]

I'm getting a 403 but it's not immediately obvious as the error I get is this:

Traceback (most recent call last):
  File "scheduler.py", line 218, in run_schedule
    _run(dryrun)
  File "scheduler.py", line 187, in _run
    data_available = report.check_data_availability()
  File "/home/thomas/gastatsdash/Statsdash/report.py", line 143, in check_data_availability
    check = self.data.check_available_data()
  File "/home/thomas/gastatsdash/Statsdash/Youtube/aggregate_data.py", line 42, in check_available_data
    data_available = analytics.data_available(id, self.period.get_end())
  File "/home/thomas/gastatsdash/Statsdash/Youtube/analytics.py", line 106, in data_available
    results['rows']
TypeError: 'NoneType' object has no attribute '__getitem__'

but in the error logs it's a bit clearer:

WARNING 03-10-2016 12-38-33 analytics->execute_query HTTP error 403 occurred:
{
 "error": {
  "errors": [
   {
    "domain": "global",
    "reason": "forbidden",
    "message": "Forbidden"
   }
  ],
  "code": 403,
  "message": "Forbidden"
 }
}

It'd be nice to be able to see this when running the command manually
