Velocity errors are affecting the rendering of the edit mode

[bryanboza]

Related to #15640

After this fix, we need to continue rendering even though the page has some velocity errors, but in this case, this is affecting the rendering of the edit mode

Expected Behavior

On those cases, we need to render normally the edit mode

Current Behavior

We are duplicating content, and showing this in other containers SC: http://www.screencast.com/t/aOIEoAo2ZNed

Also, we have an error on logs: https://gist.github.com/bryanboza/7a135e8f2a64cb1ab53bfc0b9c999bc5

Steps to Reproduce (for bugs)

1. Create a new page
2. Add a new simple widget with this code

   $estool.search({
   'query' : {
       'match_all' : {}
   },
   'size':  10
   }");

3. add a normal piece of content (generic)
4. Create a new widget with the same code
5. Navigate through tabs, edit, preview, live

Your Environment

Tested on master // Postres // FF

Even tho this is not the BEST approach to handle this errors we're good for now. Closing as @wezell requested.

We need to fix that since this happens just in the new edit mode, in previous versions we don't have the velocity error and we just print a $code SC: https://screencast.com/t/wRFY0f0nrju

After the changes, now I'm unable to reproduce the error, but we need to improve the log error in order to avoid showing too many lines of error in the log file, I think we need try to show 10-15 lines maximum in this case

[wezell]

I believe in most cases, we need to see the error in the logs. We could do better but I think this can pass for now.
