mesos git commit: Fixes `FutureTest.After3` flakiness.

Fixes `FutureTest.After3` flakiness.

Adds calls to `Clock::pause()`, `Clock::advance()` and
`Clock::settle()` to `FutureTest.After3` therefore ensuring
that data stored in timer's callbacks is destroyed by the
time `Clock::settle()` returns.

This is possible after a bug fix which caused timer's
callbacks to not always be deleted before `Clock::settle()`
returned.
