FXIOS-213 ⁃ [XCUITests] New failures after Xcode 11.3 update

[isabelrios]

There are several test suites affected:
-Tracking Protection: failure to open ETP menu from website
-Translation: Not possible to tap on the snackbar menu when loading a test site, it is possible if the site is a real one
-SyncUI: Elements in the fxa login view are not seen by the tests and so tests fail due to error in asserting the view/typing in Email field and similar
-Navigation: tests related with previous features (sync)
-HomePageSettings: error when trying to go to BrowserTabMenu

Investigating these issues and disabling the tests in the meantime...

These are the tests still having a workaround or being disabled due to iOS 13.3. The rest were fixed after the 13.4 update. Most of these could be fixed too but not done yet.
-testSearchEngine
-testChangeNewTabSettingsShowCustomURL
-testBookmarksAwesomeBar -> Disabled
-testTopSitesOpenInNewPrivateTabDefaultTopSite
-testSetCustomURLAsHome
-testSetFirefoxHomeAsHome -> Disabled

I will try these out on Xcode 11.6 and see if they still fail on simulator. I'll post a PR for the ones that pass.
