Attempt module roots resolution before others
Attempt module roots resolution before others

On the particular case of `yarn bazel test //packages/core/test/render3` in https://github.com/angular/angular I observed a 25% smaller test time.

Similar improvements can be expected in other workspaces where there are also many modules built from source.

See https://github.com/angular/angular/issues/27425 for more information.
