Exception while generating XSLT when using custom functions from different files

[chris-w-dev]

Describe the Bug with repro steps

When you use multiple custom functions in a map definition and each custom function is defined in its own XML file in folder Artifacts\DataMapper\Extensions\Functions, the XSLT generation throws the below exception.

Both functions show up just fine in the designer, even after reopening the map:

@DanielleCogs this looks like it may be a backend issue rather than a frontend issue. Could you get this in front of them?
