Allow --incremental to add spares to an array.
Commit 3a6ec29ad56 stopped us from adding apparently-working devices to an active array with --incremental as there is a good chance that they are actually old/failed devices. Unfortunately it also stopped spares from being added to an active array, which is wrong. This patch refines the test to be more careful.
