fix: deletes send their removal after the reply; test_reboot waits for the restart

- shadeRemoved, groupRemoved and roomRemoved went out from the deletes,
  before the edit's reply. They now come from editChanges and go out with
  the edit's other events, after it (test_adding_and_deleting_a_room).
- test_reboot reconnected in the moment between the sockets closing and the
  restart, and waited for a hello that never came. It now waits, retries a
  connect without hello, and checks the uptime went back.

e2e on the device (esp32s3dbg): 72 passed, 3 skipped.
