non-existent user timeout

[LockDzn]

Actual behaviour: When we try to time out a non-existent user, he returns No response from Twitch., after that if we try to time out again in an existing user he receives the timeout but returns the errorNo response from Twitch.

Expected behaviour: We try to timeout a user, if the user does not exist, it will return No response from Twitch., then if we try to timeout a user that exists, the timeout will be applied.

Error log:

timeout for usertest!
timeout could not be applied! Error: No response from Twitch.
timeout could not be applied! Error: No response from Twitch.
