bug in docker.DockerContainer.log() when container run with tty=true

## Long story short

I have a container running with tty=true
When i run docker.DockerContainer.log() with `tail`>1, the output i get is broken.
When i run len() on the list output im getting different results.
When i try to iterate on the list the output is also broken.

There is no such problem if i run the container with tty=false.

## How to reproduce
Run container with tty=true
```
docker = Docker()
container = await docker.containers.get()
result: list[str] = await container.log(stdout=True, stderr=True, tail=5)
print(len(result)) # different output every time

for i in result:
print i # getting broken output
```
