Expect the Master routing tab and menu entry in e2e 38 and 46 (#351)

CI task 590 for 0e73fd8 (#351) was red in two checks that did not
know the new Master routing yet. The product is right, the checks
were behind.

- e2e 38: the routing tab, opened by e2e 34 in the same run, is a
  document and may sit behind the plugin tab. The check now accepts
  every kind of document there, not only lists and assets.
- e2e 46: the menu lists "Master routing" after "Project settings…".

Tests:
- e2e 38 + 46 (melektaus-atx): ALL PASSED, 48 checks.
- Counter-probe: CI task 590, the old expectations were red in
  exactly these two checks.
