Bug report? Copying a theme

Tonight I used bin/plugin devtools new-theme to make a copy (machineCopy) of the Machine theme which I had significantly modified.

When I switched to the copied them I just got an essentially blank page with a statement that the theme machineCopy doesn't exist.

After digging around I saw that almost everywhere "machine" had been changed to "machineCopy". The one place I found where it wasn't changed was in the block below.

After I changed user/themes/machine to
user/themes/machineCopy, it worked fine.

# Grav streams
streams:
  schemes:
    theme:
      type: ReadOnlyStream
      paths:
        - user/themes/machine

@ranman, I'm afraid I can reproduce the issue when copying an inherited theme. Updating the stream fixed the issue.

Please create an issue at the repo of Grav or the devtools plugin.
