Subject: [PATCH] Fix `before` and `since` filter for `docker ps`

This fix tries to address the issue raised in 35931 where
`before` and `since` filter for `docker ps` does not work
and returns an error
```
Error response from daemon: no such container <container_name>
```

The issue was that `before` and `since` filter are matched
with `view.Get()` which does not take into considerations
of name match.

This fix fixes the issue by adding additional logic for name
match.

This fix fixes 35931.
