Issue description

Current behavior: Setting a [min] date for the nb-datepicker on a reactive form control that is not required. Setting the date, and then clearing the date causes the form validation to be invalid with { errors: { nbDatepickerMin: { actual: Invalid Date {}, min: Fri Jan 01 2021 00:00:00 } } }

Expected behavior: Clearing the date should set the value to empty string or null (I've tried both) and still be valid upon submit.

Steps to reproduce: Set the date. Then clear the date. the form control is now invalid
