Summary:
Fixes an issue where `scripts/objc-test-ios.sh` would fail if `xcpretty` is not installed. As this tool is not bundled with macOS, and it's not explicitly called out in our docs on testing, the script should not fail if it's not present.
In a related change, JUnit reports are written to a more sensible location when the script is run outside of Circle CI.
