wakatime-cli: Cannot read remote files through ssh

As discussed in https://github.com/wakatime/wakatime-cli/issues/426, waketime can not read remote files through ssh. I tried to make a minimal reproduction sample in this issue.

Steps

1. ssh 124.16.139.208 -p 10722 login without password currectly.
2. wakatime-cli --entity ssh://124.16.139.208:10722/home/wangtianshu/test_project/test.py got error

Configs

~/.ssh/config: empty ~/.ssh/knwon_hosts:

[124.16.139.208]:10722 ssh-ed25519 AAAAC3***
[124.16.139.208]:10722 ssh-rsa AAAAB3***
[124.16.139.208]:10722 ecdsa-sha2-nistp256 AAAAE2***
