Cleanup Apex E2E-test base class
It didn't really lend itself well to extension, so refactor the code to
have util methods like install, reboot, uninstall that subclasses can
use to write more involved test cases.
While here, make some other improvements:
- remove double-triggering of additionalCheck()
- use Truth consistently instead of a weird mix
- other readability improvements, like shortening lines, tweaking msgs
