SNPRC Scheduler Fixes

[labkey-martyp]

Rationale

Recent NPM and JSON updates resulted in some issues in the SNPRC scheduler. NPM and package updates required some refactoring mostly around react-dnd. JSON library updates has subtle differences in helper functions and handling null values.

Changes

• Update the Drag and Drop context provider and interfaces with DraggableContainer
• Add key to ensure ReactDataGrid wrapped in DraggableContainer re-renders on state updates
• Use JSON.optString for strings with default to null
• Use JSON.isNull to check both if the property exists and if it is null.

Marty,
The drag-and-drop functionality is working correctly. However, I found a few other new issues:

1. When a new study day is added, the scheduled date field doesn't get updated until after the save.
2. Tabbing out of the study day column moves the cursor to column 1 of the procedure note row.
3. After adding a Study Day note the icon doesn't get updated until one of the check boxes is clicked.

I pushed an update that should fix #1 and #3. I'm not able to repro #2. We can discuss more in the meeting next week, but you can try out the other two when you get a chance.

Other than the one minor UI problem we talked about, everything seems to be working fine. Let's merge it and worry about the UI later.
