Description of the changes

Fixes following trace:

Exception in command 'info'
Traceback (most recent call last):
  File "/usr/lib/python3.6/site-packages/discord/ext/commands/core.py", line 62, in wrapped
    ret = yield from coro(*args, **kwargs)
  File "/usr/lib/python3.6/site-packages/redbot/core/core_commands.py", line 76, in info
    data = await r.json()
  File "/usr/lib/python3.6/site-packages/aiohttp/client_reqrep.py", line 730, in json
    headers=self.headers)
aiohttp.client_exceptions.ClientResponseError: 0, message='Attempt to decode JSON with unexpected mimetype: text/plain; charset=utf-8'

The above exception was the direct cause of the following exception:

    yield from ctx.command.invoke(ctx)

Bread, your error is not the same error. Your error is in events.py, not core_commands.py

[bobloy]

core/events.py has the same problem and should be updated as well.

Replace this with session.get('{}/json'.format(red_pypi)) defined above
