Effect of a click on a checkbox can be super slow

I just clicked on the "57.0" checkbox and it was so long to wait... At least we should have a spinner or something like that.

See also #150, which is more or less the same issue. Let's see if this goes away when we fix that, leaving open for now though.

I just tried on https://data-missioncontrol.dev.mozaws.net/#/release/windows/content_crashes?timeInterval=3628740&relative=0&percentile=99&normalized=1&disabledVersions=&versionGrouping=version&startTime=1519862400 to uncheck versions <= 58.0.1 and for each of them it's super slow (~20secs for each of them).

I just tried to open the same link with chrome and when I uncheck a box it took ~6secs only (which is slow but better than with firefox).
