Bug - DatePicker - Error stays when resetting the date

[kmalyjur]

The error does not disappear when resetting the invalid value of the DatePicker to a blank one by not manually deleting it.

Steps to reproduce:
https://codesandbox.io/s/determined-banzai-h2876p?file=/index.tsx

1. Write some invalid date into the text input of the DateTime component (e.g. "a")
2. Click the "Clear date" button
   => The error message and the error icon do not disappear as they should

Problem is within dateParse. If you override it making empty string a valid date, you should be good to go.
