Fhirpath function toString() is not supported

[pavlushkin]

Cannot use non string variables in a string for choice column display

That works

        choiceColumn:
          - path: "priceOverride.value"
            forDisplay: true

That throws an error

        choiceColumn:
          - path: "priceOverride.value.toString() + 'x'"
            forDisplay: true

We use fhirpath.js for it, and in fhirpath.js toString works properly, maybe it was a regression in the specific version that we use.
@pavlushkin please send npm ls fhirpath

[pavlushkin]

npm ls fhirpath

We updated fhirpath, so it should not be relevant anymore
