--no-scripts) to fail to detect composer.lock or installed.json locations
due to getcwd() misbehavior during composer installation.

Total issues resolved: 2

• 101: Cannot locate composer.lock nor installed.json when using package with --no-scripts thanks to @PhilETaylor
• 102: #101 corrected scanned locations for installed.json and composer.json thanks to @Ocramius
