error when format run on a project containing a subproject

[paulcadman]

Say you have a juvix project like:

.
├── Format.juvix
├── juvix.yaml
└── sub
    ├── SubFormat.juvix
    └── juvix.yaml

i.e an outer juvix project containing an inner subproject.

The file Format.juvix should be processed when running juvix format . from the root of the outer project and SubFormat.juvix should not be processed as it is a member of the inner project. The current behaviour is that the subproject sub is traversed. This causes an error because the file SubProject.juvix is scoped as a member of the outer project:

 error:
The top module SubProject is defined in the file:
/sub/SubProject.juvix
But it should be in the file:
/SubProject.juvix

The format command should not recurse into directories which contain a juvix.yaml file.
