test: sibling projects inherit the loading project's args

ProjectArgs loads a chain app -> lib -> leaf of LocalProjects with --debug
and a project flag. lib, loaded without .args, has to see both, and so
does its own sibling, which takes the default one level further down.
Copies loaded with `.args = {}` and with an explicit list get nothing and
exactly that list. The GitProjectSpec default is checked on the spec
itself, since a GitProject would need a repository to clone. Without the
defaults, five of its checks fail.

ProjectDependency now also loads its consumer with a project flag: the
pragma dependency must still come back with no args. Without the explicit
`.args = {}` in the pragma path it gets the consumer's flag.
