Fixes T13464. Fully-realized paths have a "path" (normalized, effective path) and a "display" path (user-facing, un-normalized path).

During transaction validation we build ref keys for paths before we normalize the "display" values. A few different approaches could be taken to resolve this, but just default the "display" path to the raw "path" if it isn't present since that seems simplest.

Edited paths in an Owners package, no longer saw a warning in the logs.
