self.redis isn't None, it's actually unset, so accessing it results
in an exception:
```

This strips the port from the client requests, comparing only the hostnames or IP addresses, and should alleviate nonstandard port and initial testing issues. Tested on Linux, Mac, and Android clients. Closes#105.
Code is from this comment:

This is instead of the commit we reverted in the previous commit.
The problem is that django keeps the connection per thread and it relies
on django itself to clean them up before/after connections.
We can't do this, because django is unaware of fastapi, so we have to
manage this ourselves.
The easiest way is to call it at the beginning of evenry route and every dep.
We need to do it for each because unfortunately fastapi may send them to
different worker threads.
This ended up being useless because of the way startlette and fastapi do
thread pools. The middleware is called in one thread, the path in
another, and the dependency in yet another.
This reverts commit 473448246f.
The code uses the django ORM which is sync, and fastapi handles sync paths
just fine. So having all of this extra code for handling async was unnecessary.
