Added a regression test for MESOS-9609.
Per MESOS-9609, it's possible for the master to encounter a CHECK
failure during agent removal in the following situation:
1. Given a framework with checkpoint == false, with only
executor(s) (no tasks) running on an agent:
2. When this agent disconects from the master,
Master::removeFramework(Slave*, Framework*) removes the
tasks and executors. However, when there are no tasks, this
function will accidentally insert an entry into
Master::Slave::tasks! (Due to the [] operator usage)
3. Now if the framework is removed, we have an entry in
Slave::tasks, for which there is no corresponding framework.
4. When the agent is removed, we have a CHECK failure given
we can't find the framework.
This test runs through the above scenario, which no longer crashes
given the fix applied.
