PHPCSDebug/TokenList: minor tweak for testability

When a token only contains new line characters, a trailing space would be included on the line.

This makes testing the sniff harder as trailing whitespace is typically trimmed from a file, including in the expectations set in the tests.

This minor tweak ensures that the output for "new line only" tokens won't have trailing whitespace in the output line for the token.
