Michael Meeks 31f1ce360a crash test - cope with more complexity around re-starting.
With faster starting spare kits we can end up waiting for a state
where there are no live or spare kits, but the spare kit has already
beaten us to the punch:

[testCrashKit] (+1124ms): Killing coolkit instances.| httpcrashtest.cpp:151
[killPid] (+1124ms): Killing 1650047| httpcrashtest.cpp:257
[killPid] (+1124ms): Killing 1650071| httpcrashtest.cpp:257
[waitForKitProcessCount] (+1124ms): Waiting for kit process count: Doc Kits: 0  Spare Kits: 0 | KitPidHelpers.cpp:70
[waitForKitProcessCount] (+1124ms): Current kit processes: Doc Kits: [1650047, ] Spare Kits: [1650071, ]| KitPidHelpers.cpp:80
...
Forking a coolkit process with jailId: 09X67pOy1HAgSk9G as spare coolkit #5.| kit/ForKit.cpp:406
...
[waitForKitProcessCount] (+1558ms): Current kit processes: Doc Kits: [] Spare Kits: [1650083, ]| KitPidHelpers.cpp:94
... fail ...

Avoid this by intersecting before & after to ensure are all before are
dead.

Cleanup exposing the more problematic wait-for-zero-spare method.
