Updating configuration with logLevel sets endpoint instead

[driley-emoney]

This line is clear bug

rollbar-react-native/ios/RollbarReactNative.m

Line 205 in a25c886

config.crashLevel = [RCTConvert NSString:options[@"endpoint"]];

When you set a logLevel it actually takes its value from endpoint. Pretty egregious

@driley-emoney Thank you for the report. Fixed in 0.6.1.
