Detailed description of a problem

If the bot click on bed at same time when other bot/player click on bed and steal him they don't return any error,
The function no return an error

I attach video you can see a bit better: https://youtu.be/S5PrYqO4KRk

Expected behavior

Throw an error

How i can rerun tests?

[amoraschi]

Push some changes, but doesn't the sleeping duration vary with the server's TPS?

Yes, but the idea is not to get the sleeping duration, only they detect if bot are sleeping or not,
Because they don't return if the bot can be clicked correctly to bed

Seems this PR break the test of sleep, checking..

[sefirosweb]

@amoraschi done!

I think now is much better, (See code)

the sleep function waits until the sleep event is triggered,

If there is no error and the event is not triggered then it returns an error indicating that it has not been able to sleep
So in this way we will avoid errors that the .catch event of sleep() is never fired

I removed in the test "await once(bot, 'sleep')" because sleep now wait to this trigger

[amoraschi]

Promise should reject instead of resolve inside the setTimeout
