Subject: [PATCH] chore(build): don't use global module format in router bundle

Empty ES6 files are detected as "global" module format by
default which means that we end up with 2 module formats in
a bundle (es6 and global). This makes module loading more
complex and make break with certain SystemJS builder / loader
combinations.

Fixes #3528

Closes #3561
