Fixed a crash on the agent when handling the SIGUSR1 signal.
There were some actors that were not being destructed when
`finalize()` was being invoked. Also fixed the order of the
destruction of objects i.e., in the reverse order of their
creation.

> Project: Mesos
> Issue Type: Bug
> Components: agent
> Affects Versions: 1.2.0
> Environment: ubuntu 16.04

> Looks like sending a {{SIGUSR1}} to the agent crashes it. This is a
> regression and used to work fine in the 1.1 release. Note that the agent does
> unregisters with the master and the crash happens after that.
> Steps to reproduce:
> - Start the agent.
> - Send it a {{SIGUSR1}} signal.
> The agent should crash with a stack trace similar to this:
