Handle NSLog better - output it during tests

[talkol]

we should have NSLog available for crashes.. if detox doesn't work, usually NSLog can explain what went wrong and help us debug

if it's saved on the CI, it could also help us a lot to investigate failed test runs

also, it will be very nice to add tests based on NSLog, for example verify that during the last test, there were no console.errors or console.warnings

current implementation you can only output app logs in verbose mode, simply pass --detoxVerbose to the e2e script
