However, there are only two tests for which the internet accessibility
should really make a difference: There, {{{CohomologyRing.web_db(...)}}}
is explicitly called.
When doing {{{CohomologyRing(...)}}} or {{{CohomologyRing.user_db(...)}}},
it is tried to download the result from the web repository (unless
requested otherwise by the optional argument {{{websource=False}}}), and
if this fails, the computation is simply started from scratch, without
raising an error.
I am now trying to change the tests so that they will work both with or
without old data being present.
