Subject: [PATCH] tests: demonstrate issue with JSON patch when base adds name
 prefix

The expectation is that the base entity can be referenced by its name
with prefix, because the overlay shouldn't have to know how the base
is generated. But currently the entity is only found when using the
name without prefix.
