Selected calendar cell styles mismatched with design specs

Please verify the version of auro-datepicker you have installed

Please describe the bug

Current datepicker:

Departing date selection (range and non-range):

1. Create a datepicker and populate dates with price slots
2. Select one of the dates with a price
3. See that the price text does not change to white (should match design under expected behavior)

Returning date selection (range only):

1. Create a ranged datepicker
2. Select a departing date
3. Select a returning date
4. See that the returning date's pane is the same as the departing date (should match design under expected behavior)

Reproducing the error
