[Fix] Log the full error in the uncaughtException handler

[CommandMC]

logError can handle Error objects just fine, and will give us more information than just the name & message (which can be crucial to debug exceptions caught by this handler)

No need to review this before the release, mainly just creating this to help users with unexplained uncaught exceptions
