Notifications displayed when someone sends you a DM while you have the DM open

[taoeffect]

Problem

So when using the ssh -R 80:localhost:8000 [email protected] tunnel with grunt dev to test on mobile, I opened up a DM with myself from Desktop to Mobile, and any time I sent a DM to the phone while I had the phone open and showing the DM page, I would get a notification and the phone would buzz:

Solution

We already have code not to make a sound when the DM is active. We should likewise not post a notification in this instance.
