MAINT: remove xfail from passing test

[bsipocz]

Currently, 4 remote alma tests are failing, one of them because it is passing as opposed to its xfail mark.

The other three are a different case, locally and on CI I see certificate issues like the one below. One puzzling question is why the tests use the noa.ac.jp mirror, as I recall we kind of hard wired the ESO server not long ago.

Maybe @keflavich or @andamian could have a look? (I suppose the first failure just requires to rework the test, or maybe even removing it as its name suggests that it served as testing the documentation (test_doc_example), however now we have doctest running on the narrative docs.
