Remove send_command safety checks

Browse Source 
This checks are only important for users who use send_command directly instead of using the convience method.
As the readme clearly stats how send_command should work and any user would have run into errors if misused, these checks can be removed. If any user might misuse the function anyway, it is very likely that another error will be thrown because of that

Fix #629 and insert tests
