Fix panic in recursive cache (#16298)

There is a bug with last commit cache recursive cache where the last
commit information that refers to the current tree itself will cause a
panic due to its path ("") not being included in the expected tree entry
paths.

This PR fixes this by skipping the missing entry.

Fix #16290
