Allow Home and Dashboards to be uninstalled
Summary:
Ref T7143. This is the simplest fix for adding a new route for Home, at the cost of possibly letting users break instances. However:
- It's kind of hard to get to the option to uninstall Home anyway.
- It's hard to imagine anyone will really uninstall Home by accident, right? Right?
- Put a really scary warning on the action just in case.
Dashboards was only required because Home was required, I think, so just drop that too.
Test Plan: Uninstalled home.
