Use with groupdate results in time objects as keys (instead of date objects)

[abinoda]

When using with groupdate, the median method results in keys that are time objects, whereas with average, the keys are date objects. This then results in the chartkick labels showing times 😢

query.group_by_period(:month, :submitted_at).average(:time)

=> {Sun, 01 Apr 2018=>0.128564313333333333e6, Tue, 01 May 2018=>0.180389867753623188e6, Fri, 01 Jun 2018=>0.185993985959438378e6, Sun, 01 Jul 2018=>0.168664401069518717e6, Wed, 01 Aug 2018=>0.209151385899814471e6, Sat, 01 Sep 2018=>0.140354274944567627e6}

query.group_by_period(:month, :submitted_at).median(:time)

=> {2018-04-01 00:00:00 UTC=>46613.5, 2018-05-01 00:00:00 UTC=>51045.5, 2018-06-01 00:00:00 UTC=>26603.0, 2018-07-01 00:00:00 UTC=>39185.0, 2018-08-01 00:00:00 UTC=>15291.0, 2018-09-01 00:00:00 UTC=>24202.0}

Sorry, my original example was wrong. Just corrected it.

Hey @abinoda, make sure you're on Groupdate 4.0.2+.

That fixed it, thanks!
