Bugfix/incorrect min max

[yadue]

Min max options are working incorrectly:

If I set

minDate -> 15.06.2021, then it allows to select 01.06-15.06. First argument should be date, not this.options.minDate. Same situation for maxDate.

  private isDateSelectable(date: Date): boolean {
    if (this.options.minDate && isBefore(this.options.minDate, date)) {
      return false;    
    }
    if (this.options.maxDate && isAfter(this.options.maxDate, date)) {
      return false;
    }
    return true;
  }

This PR fixes it.
