Background.js fix: line 1347 - path fix

[YasminRodriguez1]

in js/background.js:
line 1347: chrome.tabs.executeScript(tabId, {file: "ytchannel.js", runAt: "document_start"});

It should be js/ytchannel.js, else it is not working.

@NuhaKhaled Thanks again for spotting a similar issue. This is a regression of #47, I will fix it in a while.
