Some error message use the indexed type and field path inconsistently

For instance, if in entity A I add an @SortableField annotation pointing to a unknown field, and if I embed this entity A in entity B, then I will get an error message along the lines of "@SortableField on property A#propertyOfA refers to unknown field propertyOfB.unknownField".
Here, "propertyOfB" should not appear at all: we're in the context of A.

We should have a look at existing messages and try to remove any existing inconsistencies.
