"Configurable, per project" only works with one project in tree-view

[rustp]

Hello!

I'm on OSX 10.12.4 / atom 1.16.0.
When I try to add a second project in tree-view I can't configure atom-gdb-debugger for it.
It always switching to the first project in tree-view.
Opening the project in a new window resolves the issue.

I's there any config file for atom-gdb-debugger in the root-directory of the project?
