Madie production FQM-Execution-Execution bug

[mcmcphillips]

Summary

When running FQM execution with the provided measure bundle and patient bundle, an error is thrown specifying an iterable. Elm for supporting libraries does not appear to have any issues.

` error occurred in FQM-Execution TypeError: The following error occurred in the cql-execution engine: intervals is not iterable

- Inspect the content of the ELM and ensure the data types in the expressions are correct

@JSRankins, @mcmcphillips Thank you for bringing this to our attention. @elsaperelli and I traced this error back to an issue in cql-execution that caused calculation to fail when collapsing a null interval.

From AHAOverall.cql Library:

when Event is MedicationRequest then
                  First( ( collapse (Event.dosageInstruction.timing.repeat.bounds DoseTime
                                        return DoseTime.toInterval()) ) DrugPeriods
                           sort by start of $this ) overlaps after day of ModerateOrSevereLVSDHFOutpatientEncounter.period 

The MedicationRequests included in the Patient Bundle do not have values for dosageInstruction.timing.repeat.bounds[x], so DoseTime.toInterval() was evaluating to null. Cql-execution's interpretation of collapse had a small logic issue that caused the argument of the collapse function to be iterated over before checking if it was null hence the intervals is not iterable message. We submitted the above PR to cql-execution, and were able to successfully run calculation with your bundles after these changes.

This has been fixed and published to npm in cql-execution v3.0.0-beta.5 and fqm-execution v1.1.0.
