CreateProject: Explicitly set parent to All-Projects when not specified

When the parent is not specified, and the project's other settings
are all default, no project.config file is created on refs/meta/config.

This prevents metadata updates from working as expected when they
result in a file being removed.

Explicitly set the parent to All-Projects when not specified, so that
a project.config file gets created on refs/meta/config.
