unit tests and surveyinit failing with new tile file

[sbailey]

desimodel/data/footprint/desi-tiles.fits has been updated, including moving the GRAY tiles to layer 0, which apparently breaks desisurvey unit tests:

======================================================================
FAIL: test_overlap (desisurvey.test.test_tiles.TestTiles)
----------------------------------------------------------------------
Traceback (most recent call last):
  File "/global/common/software/desi/cori/desiconda/20190804-1.3.0-spec/code/desisurvey/master/py/desisurvey/test/test_tiles.py", line 44, in test_overlap
    self.assertFalse(np.any(tile_over[DARK1]))
AssertionError: True is not false

I think this is also breaking surveyinit in the minitest notebook (and thus blocking our standard reference run for a software release):

@dkirkby I thought desisurvey had previously been updated to support the new tile file, but then we (I) waited a long time before merging it and desisurvey may have broken again. Could you check this out? Thanks.

IIRC this just requires a tweak to the config/rules yaml files. I can look at this tomorrow.

[sbailey]

@schlafly thanks. I'll reassign this to you to investigate.

This is expected to be addressed in #111 but I may not be appropriately setting up the environment at NERSC to test this. Travis still complains of a unit test error which I am unable to reproduce. I did:

source desi_environment.sh master
python setup.py test

in desisurvey. That should be adequate?

This is basically the same as @michaelJwilson's fix-config branch.

fixed by #111. Traivs testing problem was due to Travis tests using old tile file. Closing.
