Fix commissioning error handling in darwin-framework-tool to be more …

…like chip-tool.

For some reason, we sometimes get OnPairingComplete with an error in cases where
the same code (same YAML test) running on a different system gets a
OnStatusUpdate instead.  chip-tool handles OnPairingComplete with an error by
calling OnStatusUpdate, which steps through the test to the next test.
darwin-framework-tool should do the same, when running YAML tests.

Fixes project-chip#19276
