Can't change date preview input labels if no default value

If preview date is enabled and there's no default value to the date range. Labels are showing "Early" and "Continuous".

[BUG] Bug Reproduce Steps

Use a date range picker, provide a ranges props like the one below. <DateRangePicker ranges={[{ startDate: null, endDate: null, key: 'selection' }]} />

[BUG] Expected behaviour

Can pass custom labels to input date preview. Something like: <DateRangePicker ranges={[{ startDateLabel: 'Start Date', startDate: null, endDateLabel: 'End Date', endDate: null, key: 'selection' }]} />

Environment

Package Version: ~1.0.0-beta React version: ~16.8.6 Node version: v10.15.3 Browser: Google Chrome 73.0.3683.103

+1 for being able to change labels of "Early" and "Continuous".

FYI: You can set custom placeholder for labels Early and Continuous via props now.

    /** default: `Early` */
    startDatePlaceholder?: string | undefined;
    /** default: `Continuous` */
    endDatePlaceholder?: string | undefined;
