Add _expectOne and _expectCount about karibu-testing HOT 2 CLOSED

Maybe _expectCount() is too concrete, in a sense that why not have a _expectCaption() also. Maybe we need to introduce _expectComponent() instead:

_expectComponent<Grid> { caption = "Hello" }
_expect<Grid> { caption = "Hello" }
_expectThat<Grid> { caption = "Hello" }

_expectComponent is too long; let's go with _expect

Hmm, _expect with the default count number is pretty useless since it matches any count of selected components (thus it always succeeds). Looks like count is unique after all; I'll still go with _expect but I'll add count as a parameter straight to the _expect function.

I guess typical use-case is not to use count range, but an exact count. That's very important with the Java API which would look with int ranges like _expect(new IntRange(1, 1), Button.class) - horrible.
