Dependency recommender incompatible with configure-on-demand

[henryptung]

This commit added support for traversing project dependencies. However, the ProjectDependency.getProjectConfiguration() call assumes that the downstream project has already been notified of pre-resolution, and evaluated itself if necessary. This is not true until ProjectDependencyInternal.beforeResolved() is called. As such, errors like the following currently occur:

Configuration on demand is an incubating feature.

FAILURE: Build failed with an exception.
