regulators: Store journal messages in error logs

The Journal::getMessages() method was recently implemented and merged.
This method can be used to obtain the N most recent journal messages
from a specified application.

Modify the error logging code to use this new method.  A method call was
already in the code, but it was commented out until the new method
became available.

The journal messages are stored in FFDC files that are eventually stored
in the error log as additional debug data.

Tested:
* Test where works
  * Verify returned messages are correct
  * Verify returned messages are stored in error log
  * Journal contains 0 messages for the specified application
  * Journal contains < 30 messages for the specified application
  * Journal contains > 30 messages for the specified application
* Test where fails
  * Verify exception is written to journal
  * Verify keeps looping to obtain journal messages from other applications
