Visualizations without spy panels causing error messages

[w33ble]

Kibana version: 5.0+

Elasticsearch version: Any

Browser version: Chrome Mac 54.0.2840.71 (64-bit)

Steps to reproduce:

1. Open Developer Tools
2. Load Timelion visualization in Visualize or Dashboard
3. See errors

Errors in browser console (if relevant):

The offending line of code: $spyEl.toggleClass('only', Boolean(fullSpy));

Visualize is trying to adjust the view of vis spy panel, but Timelion doesn't have a spy.

UPDATE: This error happens on Dashboard as well.

UPDATE2: This actually happens with any visualization that doesn't have a spy panel, which includes the Markdown panel.
