EAGLESIX-2698: Just added a couple simple test cases.
Updated ObjectExpression and corresponding test cases to mongo 2.6.5.  Made a change in FieldPathExpression to make an analogous change for a failing unit test case (addDependencies()) before bailing out on the test cases for now because so many are failing.  This may be due to more needed changes in FieldPath or FieldPathExpression.
Remove debugger line from test case for ObjectExpression.js
