/**
 * Get the first event in a set of event emitters and event pairs, then clean up after itself.
 * Invoke `listener` on the first event from the list specified in `eventSpec`.
 *
 * @param eventSpec Array of arrays, with each array in the format `[ee, ...event]`.
 * @param listener Will be called only once, the first time any of the given events are emitted.
 * If `error` is one of the listened events, then if that fires first, the `listener` will be given the `err` argument.
 * `listener`'s arguments:
 * - `err`: the first argument emitted from an error event, if applicable
 * - `ee`: the event emitter that fired
 * - `event`: the string event name that fired
 * - `args`: an array of the arguments that were emitted on the event
