Bug with DatePicker when inputting date range

[Patrick-Keenan]

Bug fix in an open PR: #1236

While using input elements to update the Date Picker a user can encounter a bug where a valid date range can be rejected and set to a singular day equal to the end date.

When entering a start date with a year less than that of the end date and a MM/dd later in the year than the end date, the input is treated as if it is greater than the end date. See the first video for examples using the v-calendar guide. The bug occurs when 10/17/2019 and 10/18/2019 are entered.

This is caused by the comparison of the dates as strings rather than as date objects. The second video shows the implemented fix has solved the problem.
