Yakun Xu e611f407cd [tests] fix flaky commissioner state checks in cli-commissioner-multiple-ftds.exp (#13775)
`commissioner start` synchronously transitions the commissioner to the
`petitioning` state and prints `Commissioner: petitioning` before
`Done`. In `cli-commissioner-multiple-ftds.exp`, `expect "Done"`
consumed `Commissioner: petitioning`, and if the CoAP petition exchange
(`LEAD_PET.req`/`LEAD_PET.rsp`) completed before the subsequent
`wait_for "commissioner state" "petitioning"` ran, the commissioner had
already transitioned to `active` or `disabled`, causing `wait_for` to
time out.

Additionally, `commissioner stop` was sent without waiting for
completion before starting a commissioner on another node, and bare
`expect` / `wait_for "commissioner state"` calls matched unsolicited
`Commissioner: <state>` lines and left `Done` outputs unread in the
expect buffer.

This commit fixes the test by:
- Matching `Commissioner: petitioning` before `expect_line "Done"` on
  `commissioner start`.
- Waiting for `Commissioner: active` or `Commissioner: disabled` via
  `wait_for ""` before verifying `commissioner state`.
- Waiting for `commissioner stop` to complete and consuming
  `expect_line "Done"` after each command.
