Title: Fixes: #1905

__Scope:__ Error messages are sent to stderr stream instead of stdout/output stream.
__Fixes:__ #1905

`Composer\Console\ConsoleOutput` class scope is to use different output streams according to the outputted message type. If the message is `error`, stderr stream will be used and stdout for anything else.
