logd: fix bug in FlushTo when requesting exact sequence number
SimpleLogBuffer::FlushTo() attempts to find the iterator matching a
given sequence number, but the logic is wrong and will always skip one
element forward. This change fixes this and adds a test for the
situation.
This likely contributed to some test instability in the past, but was
identified because subsequent changes that track the start value
closer exacerbated this issue.
Test: existing and new unit tests
