test_workspaces: fix merge skew from b7c7b19 + 220292a

Summary: Yuya's changes and mine had a semantic conflict ("merge skew") between
the two of them, as b7c7b19 changed the `op log `output slightly, whereas
220292a included a new test that used `op log` itself.

Generated by `cargo insta review`.
