Preamble: this is abonineably trivial and stupid and super-corner case.
Scenario:
* Create Project "Awesome App Developers"
* use that group for years
* Today, create Sub-project {nav Awesome App Developers > Sub-project Yeah}
What happens:
The "Awesome App" project has members that cannot be edited anymore in any way.
The user interface suggests to edit its sub-Project, but there aren't.
Current workaround 1:
Create a dummy sub-project, change members from there.
Current workaround 2:
```
$ mysql phabricator_project
UPDATE project SET hasSubprojects = 0 WHERE id = <awesome app id>;
```
Proposal:
If a CLI administrator deletes the "Sub-project Yeah" from command line with the lovely workflow `./bin/remove destroy`, Phorge should probably restore its parent project as such, so, restoring `project.hasSubprojects` if that is semantically true again.
