Describe the new behavior?

This adjusts the <forge-date-picker> to open its calendar to the month of the min date when these conditions are met:

• A min date is set
• A max date is set
• The max date occurs before the current month

Otherwise if the current date falls outside the min and/or max dates the calendar opens on the month with the closest enabled dates, which was the previous behavior in all cases.

This also, and more importantly, fixes an issue where the calendar would incorrectly determine that its displayed month and year fall outside of the min or max date and unexpectedly go to the min or max date instead of the current one.

Additional information

The previous behavior was determined to be confusing when all enabled dates occur before the current month. Other possible solutions discussed included leaving the behavior as-is or allowing the month and year the calendar opens on to be manually set on the date-picker.

Closes #450
