Voice Channel remains silent after resuming the music playing, [potential problem with my resume command and resumeSong() function in music.js].

Possible Fixes:

1. Instead of using dispatcher.resume() built-in function, use my own playMusic() function in music.js
2. Possible bug in pause command despite stopping the music playing

We would like to start adding unit tests for components in our app.

Describe the solution you'd like
A test in the directory src/components/_ _ tests _ _ (creating the dir if it doesn't already exist) that tests the part of header/header.component.js which displays the profile name. (class name is 'profile-name').
