Revert "Behaviour change: now gather console logs since launch, instead of 24 hours"

This reverts commit d15b3fbc1941eb845c9da2b06ba050bfa9e75503.

It wasn't a good change because if checking for crashes at launch,
the process has only been alive a few seconds and you want older
console information than that.
Fixed spelling typo in comment
NSLog some unicode in applicationDidFinishLaunching in test app

Always having this text in the console logs ensures unicode doesn't get broken.
