Between 5.0 and 5.1, the step of incrementing the global query id changed, which broke how the profiler noticed when a new query had started. That reset the state list and caused all but the last five (or so) states to be thrown away. Now, don't watch for query_id changes in the lower level. Add a bogus state change at the end of profiling so that the last real state change is timed. Emit source reference for the start of the span of time instead of the end of it.

# server should work in the future -- or it forces everyone who
|
|
# changes the server significantly to record the test results again,

# and that violates the spirit of our tests. Please don't include

# execution-specific data here, as in all of the "show profile" and
