Number of ran tests and seconds in "Totals" aren't matched each other when stestr run --until-failure

I noticed that the number of ran tests and seconds aren't matched each other.

The number of tests shows the sum of execution number of runs tests, but the seconds shows the only for one time execution. Belows are the example.

Ran: 110 tests in 5.4677 sec.
   :
Ran: 111 tests in 5.2347 sec.

$ stestr run --until-failure ......

Is this related to #119?

Sort of, this is basically caused by the same thing that's causing #119. The elapsed time value is generated by doing a time delta by checking the time before and after the tests are executed. Depending on how we fix #119 we'll fix this too.

OK, thanks, maybe, I'll dig it later.
