No class to identify start or end of the date range, while hovering, on multi-dates if one date is selected

[Turito]

Describe the bug Since v8.3.0 (I think due to https://github.com/Vuepic/vue-datepicker/commit/3ce0e0a81239c0e1be6509f097ad653825982333) if you use the multi-dates mode then it's no longer possible, after selecting a date, there is no class that identifies the start or end of the date range to have custom styles for hovering.

In v8.3.0, after selecting a day then:

• Class .dp__date_hover is added on all enabled days.
• Class .dp__date_hover_start is added on all days disabled and less than the selected date.
• Class .dp__date_hover_end is added on all days disabled and higher than the selected date.

In v8.2.0, after selecting a day then:

• Class .dp__date_hover_start was added on all days less than the selected date.
• Class .dp__date_hover_end was added on all days higher than the selected date.

To Reproduce Steps to reproduce the behavior:

1. Go to this demo vue-datepicker@v8.3.2
2. Click on a random date to select it.
3. Hover on another non-selected date and see that there is no class that identifies the start or end of the date range

Expected behavior The expected behavior would be the same of the v8.2.0

• Class .dp__date_hover_start will be added on all days less than the selected date.
• Class .dp__date_hover_end will be added to every day after the selected date.
