Kibana crashes with fatal error if user clicks on Fit Data Bounds at certain zoom levels(when the map has no data points for that particular zoom level)

[bhavyarm]

Kibana version: OSS master

Elasticsearch version: OSS master

Browser version: chrome latest

Browser OS version: OS X El captain

Original install method (e.g. download page, yum, from source, etc.): Built from master

Description of the problem including expected versus actual behavior: When I click on Fit Data Bounds at zoom levels with no data points(?), Kibana crashes with a fatal error.

Steps to reproduce:

1. Create a map with makelogs data
2. zoom in to map and stop where you can't see any data points
3. Click on Fit Data Bounds - Kibana crashes with fatal error and reloads the map(Reloading happens only sometimes)

Errors in browser console (if relevant):

@thomasneirynck as a heads up I just ran into this on master when clicking the fit data button before loading an aggregation

@jbudz I'll reopen this, thanks

this also occurred in the case when no data was loaded, not just when zoomed in on a spot that showed no data.
