This fixes a bug where the command is not showing in the <gr-upload-help-dialog>, see referenced issue. Apparently `readOnly` does not allow you to initialize it along with its declaration, which is what we were trying to do: https://polymer-library.polymer-project.org/2.0/docs/devguide/properties#read-only Also import lodash in all tests that rely on it.
