Fix android tests for v2.0.3

This MR includes minor fixes for issues found when running the androidTest code, and it updates several of the tests to work with v2.0.3. Specific fixes include,

• Excluding url's containing localhost from being rewritten with https://, fixes tests that use MockWebServer as well as the unlikely case that someone might want to access something at http://localhost
• Use customLoadUrlUseCase when a HistorySuggestion is selected from AwesomeBar, solves issue with transitioning to BrowserFragment
• Use onStopListener to handle transitioning to BrowserFragment after SearchSuggestion is selected AwesomeBar, which is just a refactor of a previous solution
• Fixing various issues with test code, mostly related to the change to the home page not having a placeholder tab
