Moved class into correct package.
Removed unnecessary asset location within brjs conformant libraries.
Deleted JsLib.getRootAssetLocation() as it's no longer required.
Provide better failure messages within hasSourceModules() and
hasAssetLocations() so we don't need to keep debugging the tests when
there is an assertion failure.
Updated brjs thrirdparty test so it should now be correct, even if it is
currently still failing.
