fix $output->section()->write() without newline output

by default, it is impossible to use write without newline when using a ConsoleSectionOutput as consoleOutput (including with SymfonyStyle : $io = new SymfonyStyle($input, $output->section()))

this PR allow a section to work like a normal output when using write() method
