Can't remove DateTimes from a typed list

[nshki]

Hello! Thank you for this wonderful gem. I came across a behavior today that could possibly be a bug—when trying to remove a DateTime instance from a typed list, it doesn't seem to work.

Here's some code that I ran in a Rails console to replicate:

datetime_list = Kredis.list("testing", typed: :datetime)
datetime_list.append([1.minute.ago, 1.hour.ago, 1.day.ago])
datetime_list.remove(datetime_list.elements.first)
datetime_list.elements #=> Still has 3 elements

This works if I don't specify typed:

datetime_list = Kredis.list("testing")
datetime_list.append([1.minute.ago, 1.hour.ago, 1.day.ago])
datetime_list.remove(datetime_list.elements.first)
datetime_list.elements #=> Only has 2 elements, so it worked!
