Repeatedly clicking on a playlist duplicates playlist entries

Description
When I click multiple times (fast) on a playlist, e.g. double clicking, the playlist entries and song counter are duplicated. It seems that having more than 100 items in the playlist makes the problem better visible.
Clicking on a playlist multiple times should not duplicate the entries and song counter.
The problem occurs in gnome-music 3.16.1 on Korora 22 (Fedora 22) and I reproduced the same problem in 3.17.5 on the master branch.
