NullPointerException when loading/compiling dependent CQL libraries (FHIR Helpers)

[vitorpamplona]

Describe the bug

CQL Compiler runs into an Internal Translator Error when processing dependent libraries.

Component
Workflow module

To Reproduce

1. Create a CQL with a dependent library (e.g. FHIR Helpers)
2. Create an FHIR Library with a text/cql attachment of 1.
3. Try to evaluate the library in a given patient.

The stacktrace should be:

Expected behavior
The compiler should find, compile and load dependent libraries.
