Fix testCull methods to correspond to current behavior of block closures.
Existing test failures were masked by test methods that required recompilation.

Subject: Re: [squeak-dev] Why isn't BlockClosureTest>>testCull failing?
I think that behavior was changed not too long ago (1-2 years maybe). If
you decompile the method you'll see that it's actually
self
assert: 1
equals: ([:x | x]
cull: 1).
It's because Squeak used to return the value of the last argument if the
block was empty, but had arguments.
The code should be
self assert: nil equals: ([ :x | ] cull: 1).

No need to query which selector isDoIt, because DoIt methods are not installed anymore in the methodDictionary (for a few years yet).
