test: Fix flaky battery aggregation test

It seems that the test was still flaky, the reason for that would be
that we did not explicitly wait for the log line saying that the
aggregate state was calculated.

The only reason that it did not consistently fail appears to be that
searching for the state conflict caused messages to be skipped. That is
wrong, we should account for every "Calculating percentage" message to
ensure that upowerd and the test is in sync.
