• Fix Tests fail silently if they have the same name as other tests #447 - Tests fail silently if they have the same name as other tests. Now we will track test uuid to monitor failed/passed tests
• Now we are using test uuid in screenshot names, when uniqueScreenshotNames: true
• Remove obsolete util HashCode

UUID is provided by mocha?
Does it generating every new UUID for each new test run?

@DavertMik Yes, Mocha generates UUID for each tests and hook. If you set retries for tests then every retry will have the same UUID. Mocha generates new UUID for test each new test run
