QCommandLineParser: Ensure that an option text ends with a newline

Before this change we inserted newline only if an option has a
description and ended up with an arbitrary long line with all options.

[ChangeLog][QtCore][QCommandLineParser] Fixed a bug that caused the help
output to show two options or more in the same line if the options didn't
have a description.
