Runtimes in journal_event break plugins

**Describe the bug**

Code in EDMarketConnector.py:journal_event() is not in any try:except blocks. The result is if anything runtimes event processing stops which can break any plugins that depend on the journal event. I've had this happen in at least two circumstances. One where the ships.json wasn't up to date triggering a key error and now when someone had misconfigured their output directory.

**To Reproduce**
It's hard to give specific directtions. If you clear your output directory but enable ship loadout exports no plugin will receive any Loadout events because EDMC errors before that code.

**Expected behavior**
EDMC catches the runtime and still calls plug.notify_journal_entry().
