Allow document to be undefined for REPL support

Justin Holguin · Justin Holguin · commit c319b2b377d1 · 2017-10-13T12:03:00.000-07:00
Previously, attempting to start elm-repl for a module that depends on
Navigation would fail because `document` was undefined. This commit uses
a dummy (empty object) value for the offending reference, preventing a
crash.
