No refresh button in docs addon after adding first reference with chrome plugin

Just a bug report, reasonably minor and can be fixed by closing and reopening the google docs addon or refreshing the page.

To reproduce:

  • Have both the docs addon and chrome plugin installed
  • Create a new doc
  • Open the docs addon sidebar
  • Add a reference to your document using the chrome plugin (ctrl+alt+p)
  • Try to refresh the docs addon sidebar

The refresh button on the sidebar isn’t visible yet, it only shows up once there are already references in the sidebar.

Proposed solution:
Add the refresh button to the sidebar when there aren’t any citations being shown

Nice catch, thanks.
