KeyError: 'show_bounds' when setting projection

ALL software version info

geoviews 1.7.0a3 bokeh 1.4.0

Description of expected behavior and the observed behavior

Complete, minimal, self-contained example code that reproduces the issue

This will plot correctly:

gv.Polygons([[[-88.8, 1], [-88.81, 30], [-60, 30], [-60, 1]]], crs=crs.PlateCarree())

But this will throw an error:

gv.Polygons([[[-88.8, 1], [-88.81, 30], [-60, 30], [-60, 1]]], crs=crs.PlateCarree()).opts(opts.Polygons(projection=crs.Robinson()))

I’ll also note that running the broken code above on gv 1.6.6 does not throw an error

Note that this is already fixed on master.

Thanks. I’ll release a fix later today.
