Improve test coverage for Measure.createTuplet

[massimobio]

We need a failure test that throws MeasureError.invalidNoteRange for the Measure.createTuplet method.
There is a failing test stub in MeasureTests.swift testCreateTupletNoteInvalidNoteRange() that needs to be fixed

I made a separate TODO for making a test that exercises this error case below the mentioned test because that test is useful as is. So, it would still be nice to write a test to exercise this error case.
