[Merged by Bors] - fix: remove second type from test in order.lean

[vasnesterov]

When the order tactic fails, it prints all the types it was run on. The order in which these types are printed is arbitrary, and any changes in the transitive imports of order.lean can change this order and cause the test to fail.

For example #mathlib4 > MathlibTest.order error

This PR removes the second type from the test.
