javascript fails to set the hidden value when the remove icon is clicked

[daveisagit]

Describe the bug
Script should allow for a null date value

To Reproduce
Steps to reproduce the behaviour:
You can reproduce this on your demo pages

1. Enable a date input picker with the remove icon
2. Use the remove icon and the hidden value is not nulled out, and so the form action uses the last value entered.

datepicker-widget.js:119 Uncaught TypeError: e.date.format is not a function
at HTMLDivElement. (datepicker-widget.js:119:41)
at HTMLDivElement.dispatch (jquery-3.5.1.min.js:2:43090)
at v.handle (jquery-3.5.1.min.js:2:41074)
at Object.trigger (jquery-3.5.1.min.js:2:71513)
at HTMLDivElement. (jquery-3.5.1.min.js:2:72108)
at Function.each (jquery-3.5.1.min.js:2:2976)
at S.fn.init.each (jquery-3.5.1.min.js:2:1454)
at S.fn.init.trigger (jquery-3.5.1.min.js:2:72084)
at h (bootstrap-datetimepicker.min.js:1:7860)
at g (bootstrap-datetimepicker.min.js:1:13676)

Expected behaviour
The field should be represented with a None value

on line 119 e.date will be null in this case
hiddenInputElement.value = e.date.format(config.backend_date_format);
