ddev rm -RO <projectname> does not remove a non-running project line from global_config.yaml

[rfay]

Describe the bug

This mostly matters for cmd tests that try to remove sites just to clean up, but it should be fixed in general.

The reason it doesn't work in the cmd tests is that ddev rm -RO <projectname> doesn't work if the project is not currently running or stopped.

To Reproduce

mkdir junk && cd junk
ddev config --project-type php
ddev rm -RO junk

You'll see the junk project (added by ddev config) is still in ~/.ddev/global_config.yaml

Also:

• Run the cmd tests. You'll see lots of crap in the global_config.yaml afterwards.

Expected behavior

• ddev rm -RO should work even if project has been rm'd or never even run.
• tests should not leave crap in global config

This issue should fix both issues
