flip_test: don't skip checks for sequence #1
flip_test: don't skip checks for sequence #1

So far we skipped some tests for seq#0 and #1, since at that point we
were missing the 'last' state against which we could compare the current
state. Since in the previous patches we fixed the ordering in the test
loop and moved the increment of count to the update state phase, we have
a proper 'last' state for seq#1, so enable the tests already at that
point.
