Tokens get sanitized even when they shouldn't

Problem/Motivation

Module code is running check plain on tokens value even when the sanitize option is set to false in function title_tokens_alter.
This results in some characters are not rendered correctly, for example apostrophe.

Steps to reproduce

Create node title with apostrophe and use it in token.

Proposed resolution

In related issue there was already fix for that, but was removed later on. Adjusting it and bringing it back should fix the problem.
