Menu page deselection issue

[itshuey]

Currently, the menu page is set up to track the current selection across different days. This is a great feature, but it deselects when you change days to one without the current meal type. For example, if you select breakfast on Monday, and then click on the Saturday tab, you will see the misleading message:

No dining halls open at this time. Try another time!

This is because Saturday does not have a breakfast meal type (it has brunch instead). If it defaults to auto-selecting the first available meal type, we can circumvent this issue!
