Some small edits to existing examples. I suggest removing one of the examples entirely, but feel free to keep it if you feel like it's justifiable. Good work!

@bsipocz I think this is ready to merge. Let me know if you have any other suggestions for this. Thanks!

All the examples cause test failures as the tracebacks are not properly added to the docs. I'll just quickly push a commit and fix it. I'll also rebase to be sure we're all good as there have been a few other PRs since this was branched out, that modified this documentation page.

For the next time, I would suggest to run the remote tests until they are all clean (for this particular case pytest docs/mast -R)

[bsipocz]

This produces a test failure as the error is not exactly copy pasted.

@jaymedina - the following isn't issue the warning any more, so I also removed that as part of this PR to make sure all the docs is passing:

    >>> from astroquery.mast import Tesscut
    >>> sector_table = Tesscut.get_sectors(objectname="Ceres", moving_target=True)

Thanks @mstcyr2!
