[BUG] set_account_data and get_account_data not working correctly

[jostrk]

Describe the bug
When trying to use set_account_data and get_account_data we encountered the following error:

/venv/lib/python3.9/site-packages/niobot/client.py:1479: RuntimeWarning: coroutine 'AsyncClient.send' was never awaited
  async with self.send(method, path, data, {"Content-Type": "application/json"}) as response:
RuntimeWarning: Enable tracemalloc to get the object allocation traceback
ERROR:bot:Command "hello" error: __aenter__

Additionally it seems that both get_account_data and set_account_data do not pass the necessary authorization headers to the underlying (matrix-nio) send function.

Finally set_account_data seems to expect a json object rather than the dict as defined in the documentation:

set_account_data(
    key: [str], data: [dict], *, room_id: [str] = None
) -> None

To Reproduce

d = {"test": "value"}
await self.bot.set_account_data("test.type", d)
val = await self.bot.get_account_data("test.type")

I've got a feeling that I forgot to await a coroutine while writing this, should be easy enough to fix. I'll take a look in a couple hours when I'm at a PC, thanks for the report!

Thanks a lot, I can confirm it works now, except for the type of the data object.

It seems we need to send a json, rather than a dict:
d = {"foo": "bar"}
res = await self.bot.set_account_data("test.type", json.dumps(d))

Oh whoops sorry, totally forgot about that part! I'll have a look at why you need to pass JSON because that's definitely not intended.
