Fix formatting for aiohttp post

[functionpointer]

Modify the formatting so that mypy is happy.

The ASYNC109 looks like a false positive to me, as the timeout parameter is consumed by aiohttp.
So i added a noqa.

I also may have spotted a bug, where the timeout parameter is never actually used.
Instead, self.timeout is used directly. This is relevant in home.py:535, where historic data is fetched with a hard-coded timeout of 30s (in contrast to default 10s).
Given the longer timeout was never actually used, it may also be reasonable to remove the timeout parameter entirely.
