WMI exploiter hangs

[mssalvatore]

Describe the bug

It seems that the WMI exploiter can sometimes hang, resulting in agents that remain running even though their mission is complete. The agent must be stopped by clicking the "Kill All Monkeys" button on the Infection Map.

To Reproduce

Steps to reproduce the behavior:

1. Use the test-2 environment
2. Use v2.2.1
3. import the attached monkey-config.txt (GitHub won't allow a .conf file to be uploaded) monkey-config.txt. Config in the comment below
4. Run the agent from the Island
5. After all propagation is complete, you'll notice that agents on some machines, such as tunneling-9 and credentials-reuse-14 never shut down.
6. Click the "Kill All Monkeys" button
7. Once all agents are shut down, you can download the agent logs and inspect them

Notice that ExploiterThread-03 logs that a file was successfully copied, but no log messages from ExploiterThread-03 are received thereafter. In addition, every exploiter thread except 03 shuts down.
