Calling SetValue on Element/DateSelect with an empty string set's to todays date

[carnage]

If a DateSelect element has it's value set to an empty string, due to the behaviour of php's date time object; the element is set to today's date. See offending code:

zend-form/src/Element/DateSelect.php

Line 106 in 29a930f

if (is_string($value)) {

This may be considered desirable; however if the option create_empty_option is set to create a default empty option, this behaviour prevents the element from being set back to the empty option.

The fix would be to test for an empty string in that conditional, but is a potential BC break

I don't think this is a bug, but rather expected behavior (in line with DateTime's behavior).

I'd rather suggest accepting null and then nulling all fields if that is the case.
