BP Nouveau: Activity directory scope tabs count is confusing when it equals to 0

[imath]

The more i see it, the more i think we should remove the count spans when they are set to 0 from into Activity scope tabs.

In BP Nouveau, these counts are there to inform about newest activities for each scope. But when i see this, i understand no activities at all were posted in groups or mentions :

So i suggest the attached patch who makes sure span counts will only be shown when there are newest activities about their corresponding scopes.

For example, as the stream first started with no counts. When i see the above screencap, i understand better there are 1 new activity and 3 new mentions.

What do you think ?

BP Nouveau: Activity directory, remove misleading 0 count from tabs.

Into the Activity directory the count spans added to the scope tabs are there to inform about newest activities (HeartBeat) for each scope. Starting the UI with a count set to 0 can be misleading because we could believe this count is about the total number of activities for each scope.
