Chrome extension: Notification popups don't appear if hangouts extension is enabled.

[Kellett]

Chrome: Version 30.0.1599.101 m
OS: Win7
DeskSMS: 1.2.7

If the google hangouts extension (https://chrome.google.com/webstore/detail/hangouts/nckgahadagoaajjgafhacjanaoiihapd) is enabled in chrome the SMS notifications from DeskSMS don't appear and the icon doesn't display the unread count.

If you uninstall and reinstall DeskSMS extension it seems to work again until you restart chrome.
