Replace assertThat(stream.collect(toImmutableList())) with assertThat(stream)

In Truth8, we can do assertThat(stream) directly. It's less verbose and clearer
in most cases.

Note that for the "finishers" (e.g. "containsExactyElementsIn") - streams are
still not allowed. So when there is:
assertThat(stream.map(someTransformation).collect(toList()))
.containsExactlyElementsIn(expecteStream.map(someTransformation).collect(toList()));

I kept the .collect in the assertThat to preserve the symmetry with the
finisher.
