transform=ccrs.PlateCarree() now required when making maps

[bradyrx]

I think after 77f2b71, this issue arose.

Previously, one could do something like:

import numpy as np
import proplot as plot
% import cartopy.crs as ccrs

data = np.random.rand(180, 360)
lats = np.linspace(-89.5, 89.5, 180)
lons = np.linspace(-179.5, 179.5, 360)

f, ax = plot.subplots(proj='robin')

ax.pcolormesh(lons, lats, data)

and you'd get the map. Now it's showing up blank and requires ax.pcolormesh(lons, lats, data, transform=ccrs.PlateCarree()). Maybe minor but a nice thing to not have to worry about with proplot.

...sorry, that was a dumb bug. Fixed by 05c3898.

FYI @lukelbd , globe=True doesn't work anymore for me with contourf after this (or maybe before this? I'm not sure). But it fixes the seam on pcolormesh but not contourf right now. I had to manually run the cartopy add_cyclic_point.

I'm not sure how to reproduce this with simple data. It's always a mystery to me which data makes a seam.
