onClose event has wrong values inside when allowInput is set to true

[alex-w0]

Steps to reproduce:

1. Pick a correct date e.g. 2020-01-22 - 2020-01-28
2. Delete the entry with the delete button and write the word 'test' inside
3. The onClose event will now be fired and as you can see the first parameter selectedDates doesn't contain an empty array (because the input is not valid as date), instead it keeps the old start date.

At the moment I have to parse the second parameter to a date object if I wan't to get the real input values.
