[fix] skip test broken by snowflake (#239)

Snowflake appears to have changed something which is now causing this
test to fail. Skipping it for now while I find someone who can address
the problem.

cc @henriblancke  and @chriskuchin  who worked on this originally. Any chance one of you could look at this?
