refactor: streamline ReporterTestResult and imagesInfo types

[shadowusr]

What's done?

• Got rid of all ...TestResult types in favor of universal ReporterTestResult
• Got rid of assertViewResults field in ReporterTestResult
• Got rid of image-handler and made formatting imagesInfo a lot easier
• Got rid of global caches and implemented Cache class instead
• Implemented images-info-saver which performs saving of screenshots and updating paths, it's an almost complete re-write of the old image-handler
• Implemented SqliteTestAdapter, which can parse sqlite rows directly into ReporterTestResult

Why?

• Having a single a single interface like ReporterTestResult greatly simplifies the way you think about, alter and process test results across the whole app
• Similarly, having a single imagesInfo format makes it easy to support different tools and keep track of screenshots data in general
• Having explicit cache classes as well as more straightforward formatting of images makes it significantly easier to deal with image data

⚠️ Review tips ⚠️

Main chunks of changes:

1. images-info-saver — the idea of this class is to accept imagesInfo array, save images and return imagesInfo with updated paths
2. test adapters now format imagesInfo on their own, without help of external utils, because each adapter transforms unique object shape to ReporterTestResults' imagesInfo
3. Removed PreparedTestResult and similar types as well as add...() methods from report builders, it's pretty obvious
4. Other than that, very little has changed. A few enhancements here and there and tests, should be simple enough!
