Increase time interval of has-new-messages requests

[willemarcel]

Currently the frontend makes a new request to /api/v1/messages/has-new-messages each 10 seconds.

Although it's a request that returns a tiny amount of data as response, I believe we don't need to fetch it so frequently and it would help reduce the load on the server. I suggest to increase the interval to 1 or 2 minutes.

Interval function is at

tasking-manager/client/app/components/account-nav/account-nav.directive.js

Line 57 in ab03f50

function activate() {
