Indicator animation stops after reloading collection view

[jonathanfoster]

Indicator animation stops after reloading collection view and startLoading doesn't restart the animation. Looks like this has to do with UIActivityIndicatorView not restarting, but LoadyIndicatorAnimation.isLoading is never reset, you can't restart the animation.

I played around with using activityIndicator's isAnimating to indicate loading, but the title inset logic kept pushing the title back on each call. A work around is to reset the animation each time the cell is configured, but this still results in too many insets on the title.
