fix(test): Reconcile xcodebuild Swift Testing lines

Lowercase xcodebuild test case lines can represent Swift Testing
results when they use slash-separated Swift test identifiers. Treat
those lines as Swift Testing observations so a following Swift Testing
run summary does not count the same tests again.

Fixes GH-384
