[Feature Request] Add additional response to ;play command.

[Ikinon]

Is your feature request related to a problem? Please describe. It's confusing when you stop music and then type play again, or just type play without arguments with nothing in queue

Describe the solution you'd like Create an additional message saying something like "There's no tracks in queue" when there is nothing in queue.

Describe alternatives you've considered No idea

Additional context How we reply when there's nothing in queue at the moment: https://cdn.discordapp.com/attachments/599956712799207444/848940913232969748/Screenshot_20210531_160647.jpg
