Using a shared/static list of events causes event crossover

[barrywimlett]

If you create two journalWatchers then they will recieve each others events.

Using a shared static list of events means two independent journalwatchers end up recieving each other events.

In real-life people will only create one watcher and point it at %PROFILE%\Saved Games\Frontier Developments\Elite Dangerous

However confused the hell out of me when unit tests get run in parrallel.
