Bug: Resizing 0h event with same start and end time

[BlackRockSoul]

Resizing an event that has the same start and end dates cause the start date to become 'Invalid date'.

This happens because this line of code adds 1 day to 0h events for some reason.

react-big-calendar/src/addons/dragAndDrop/common.js

Lines 42 to 43 in d7c14f6

	// make zero duration midnight events at least one day long
	if (isZeroDuration) end = dates.add(end, 1, 'day')

And after that, the closestSlotFromDate function is not able to find the closest slot because the closest to the end is already the next day.

react-big-calendar/src/utils/TimeSlots.js

Lines 107 to 108 in d7c14f6

	const diffMins = dates.diff(start, date, 'minutes')
	return slots[(diffMins - (diffMins % step)) / step + offset]

It just returns undefined instead of a correct slot - offset -1 doesn't help at all.

In this case offset should be at least -49
I'm not sure if adding 1 day to an event is necessary in some particular cases, but I'd remove this - without this line, I'm not getting any errors in this case.
