Make e2e 40, 46, 51 and 52 pass in the full run again

The suite job failed on every push since 6015869. Each module passed on
its own, but the full run showed two kinds of fault.

- e2e 40 still expected the object menu and the empty-cell menu from
  before #240 and #241. It now expects Copy, Paste, Group... and Remove
  from group, and Paste alone on an empty cell.
- e2e 46g read the outline of the first collider in the scene. In the
  full run that is a leftover of module 43, off screen, so it read as
  hidden before any switch. The check now places a collider of its own
  next to its tilemap and removes both at the end.
- e2e 51 copied the seed's red and blue crate. In the full run module 09
  has packed both into a container. The module now places two crates
  with colliders of its own and removes them at the end.
- e2e 52 compared whole row lists against the seed scene. In the full
  run that scene holds about 50 more rows. The module now works in a
  scene of its own, which it removes at the end. It had never run in CI
  because 51 died before it.

The check in e2e 41 that failed once (task 347, a dragged body 15 px
off in its first sample) is left alone. It failed in 1 of the last 60
logs, while a local e2e run loaded the same host.

Tests:
- full e2e run in the game-maker-ci image with GPU, as the runner does:
  ALL PASSED, 1452 checks, E2E EXIT 0 (the README sum is now measured)
- GM_STEPS=1,46,51,52 on the host: ALL PASSED, 51 checks
