Imitate old comparison behaviour when collecting dependencies

This is needed, because previously such code were not distinguishing
between different flavours of JVM or Common. Now we do, and, for
example, JdkPlatform(1.6) != JdkPlatform(1.8), which causes such
dependencies to be erroneously dropped
