Tooling not using proper fully qualified URL for FHIRHelpers library

[mholck]

Describe the bug
When using the tooling to refresh in the ecqm-content-r4 repo when it regenerates the library JSON it is coding the depends-on incorrectly for just the FHIRHelpers library

"relatedArtifact": [ {
"type": "depends-on",
"display": "FHIR model information",
"resource": "http:https://fhir.org/guides/cqf/common/Library/FHIR-ModelInfo|4.0.1"
}, {
"type": "depends-on",
"display": "Library FHIRHelpers",
"resource": "Library/FHIRHelpers|4.0.001"
}, {
"type": "depends-on",
"display": "Library SDE",
"resource": "http:https://ecqi.healthit.gov/ecqms/Library/SupplementalDataElementsFHIR4|2.0.000"

This causes the post to the sandbox for the bundle to fail, it also includes FHIRHelpers multiple times

To Reproduce
Checkout the ecqm-content-r4 repository
run _updateCQFTooling
run _refresh

The bundles will be generated but when they post to sandbox they will fail

Expected behavior
The depends-on for FHIRHelpers should have been

{
"type": "depends-on",
"display": "Library FHIRHelpers",
"resource": "http:https://ecqi.healthit.gov/ecqms/Library/FHIRHelpers|4.0.001"
},
