[CC03] Replace expectCallback* with expect

"callback" is redundant – it's a TestCallback object and
it takes a type of callback anyway.

"assertNextIs" is shorter than expectCallback, and more
directly explicit than "expect", but it's also 3 words
and very different from previous usage.
Using expect() is a little bit less in-your-face obvious,
but it's simple, familiar, and short.
