Cache Error caused by setting another API Key

[scoronado12]

General Summary

In the wake of issue #1063, I have decided to register my own API keys to use with mps-youtube. Every once in a while that causes the following python error.

Traceback (most recent call last):
  File "/usr/lib/python3.8/site-packages/pafy/util.py", line 34, in call_gdata
    data = g.opener.open(url).read().decode('utf-8')
  File "/usr/lib/python3.8/urllib/request.py", line 531, in open
    response = meth(req, response)
  File "/usr/lib/python3.8/urllib/request.py", line 640, in http_response
    response = self.parent.error(
  File "/usr/lib/python3.8/urllib/request.py", line 569, in error
    return self._call_chain(*args)
  File "/usr/lib/python3.8/urllib/request.py", line 502, in _call_chain
    result = func(*args)

    raise HTTPError(req.full_url, code, msg, hdrs, fp)
urllib.error.HTTPError: HTTP Error 403: Forbidden

During handling of the above exception, another exception occurred:

Mitigation

To solve this, I would have to delete ~/.config/mps-youtube/cache_py_3.8.* which really should not be a full solution.

@scoronado12 Thanks for posting the fix for this, I appreciate it!

This also causes api_key issues:

pafy.util.GdataError: Youtube Error 403: The request cannot be completed because you have exceeded your <a href="/youtube/v3/getting-started#quota">quota</a>.

Given the above error, I tried using set api_key and modifying config.py. Both failed until I cleared cache_py_3.*.py
