Detect nested refs in custom classes

[posva]

What problem is this solving

The automatic binding of nested references doesn't work if .withConverter() is used. It currently only works with plain js objects See extractRefs() in utils.ts

• See When using withConverter on collection it do not fetch inner refs #1492

Proposed solution

• Safelist of classes to parse
• Automatically detect classes field while ignoring methods
