Nasty hack to fix masonry for now.

The only problem that angular-masonry is unable to solve is the issue
we’re getting when filtering products by tag/category. Here, we need to
either remove items from our masonry properly (using
addItems()/removeItems()) or figure out a better way to fire masonry
when filtering.

I explored some solutions for the latter (firing layout() for masonry
when ng-repeat finishes for example), but nothing worked until I tried
a simple timeout() solution.
