Ensure plot ranges for all renderers are combined in auto-ranging

[philippjfr]

Fixes a small oversight in the auto-ranging implementation by combining the ranges for all renderers instead of overwriting them. Also simplifies the code by using the new Bokeh.index.find_one API instead of rolling our own implementation.

Fixes #6033

• Add UI test

Updated the code to work with overlay. Can you please review those changes?

Other than that, it looks good to me; you can merge after looking at my changes.
