Resolving platform-provided dependencies from all repositories

JaywayMavenAndroidProject.JaywayMavenAndroidProject() returns all
platform-provided deps, so these can be filtered out from the
non-runtime container. The deps was resolved only from a hard-coded
central repo. With this commit, the dependencies are resolved from all
repositories related to the current project.
Added test
Added .pom to fake repository

The android artifact in the fake repository used in the remote
dependency test did not contain a .pom file. This adds the file, so
Aether does not tries to download it again in every resolution.
