TST: parametrize surveys to see which one fails

[bsipocz]

I started to see this failure in CI, the current PR refactors the test, so there is more info about which survey fails to return any results.

@szampier - is it expected that HARPS_CAT has no results? If yes, then I'll add a null result list, so we will pass the test, otherwise please let me know how to proceed.

Note: the remote test is still failing, so we shall not merge it until a solution or workaround is added for it.

@bsipocz it's an issue on the ESO side, HARPS_CAT should not be listed among the ESO surveys.
I spoke with @almicol about this and he will fix it in the ESO Archive.

BTW, in PR #2681 I "fixed" test_each_instrument_SgrAstar which was also failing. Now that I understand better what the test does, I'm not sure that the test makes sense although I'm not an astronomer. Essentially it checks that each ESO instrument has data around the galactic center, which is not true for many instruments. Maybe the test should check for a subset of the instruments similarly to what we do for the surveys, where we do this check for a subset of the surveys SGRA_SURVEYS.
My fix consists in ignoring NoResultsWarning which is not great. Maybe since you are working on this you could improve
test_each_instrument_SgrAstar as well or if you prefer I can try to do it.

The module is undergoing a full refactor and the end of that process all tests will pass. So I'm closing this without merging now.
