Log Viewer doesn't respect log entry severity when logging from cloud functions

[jaytavares]

The log viewer ignores the severity of log entries. When logging errors from cloud functions running in the emulator the entries always display with a severity of 'Info'. I tried using the standard console.error() and functions.logger.error(). I also tried logging with and without Error objects:

functions.logger.error('Error 1')
functions.logger.error(new Error('Error 2'))
console.error('Error 3')
console.error(new Error('Error 4'))

All display in the Log Viewer with a severity of 'Info' in the gutter:

I can confirm the emulator logs don't seem to respect the severity.
