Description

With the recent run modes handling changes, starting a Sling instance as an upgrade (i.e. on an existing sling folder) might define new default run modes that were not present in the old instance but need to be active on the upgraded instance.

In this case, the SlingSettingsServiceImpl needs to evaluate the run mode options against the existing run modes, in a similar way to an "install" startup.
