SkyCord print change in astropy master (beta of 3.1?)

[nabobalis]

Description

We have several doc tests fail under astropy master.
Looks like the print for skycord has changed.
We probably cant fix this until the new version of Astropy is out.

Link here.

Expected:
    <SkyCoord (Helioprojective: obstime=2017-07-26 00:00:00, rsun=695508.0 km, observer=<HeliographicStonyhurst Coordinate (obstime=2017-07-26 00:00:00): (lon, lat, radius) in (deg, deg, AU)
        (0., 5.31701821, 1.01567428)>): (Tx, Ty) in arcsec
        (0., 0.)>
Got:
    <SkyCoord (Helioprojective: obstime=2017-07-26 00:00:00, rsun=695508.0 km, observer=<HeliographicStonyhurst Coordinate for 'earth'>): (Tx, Ty) in arcsec
        (0., 0.)>

Furthermore, it seems that the doctest return of sunpy.cm.cmlist.keys() has changed width.

Expected behavior

The tests shouldn't fail

Actual behavior

The tests fail

Steps to Reproduce

1. Install astropy dev
2. run sunpy tests
3. ?
4. profit

I have no idea why this is only happening on astropy-dev. What you are describing looks like the change introduced in #2723
