Added settingsCache handling to e2e-framework

refs: https://github.com/Ghost/Ghost/commit/b5ee17b25

- When moving the site tests into e2e-api they broke because they were getting the changed settings value from the settings test
- The solution is to ensure the settingsCache is reset between tests, which is what this commit does
- This commit also renames the shutdown method to reset, because this is not a permanent operation
- It also renames the resetDb method to resetData, because the concept is we want the internal data to be reset, not just the DB
