Fix fragment cache helper regression on cache miss introduced with 03…

…d01ec.

Contains following patches cherry-picked from @lhahne's 3-0-stable branch:

* Added tests for the output_buffer returned by CacheHelper (c476a6b)
The output_buffer returned by CacheHelper should be html_safe if the original buffer is html_safe.

* made sure that the possible new output_buffer created by CacheHelper is of the same type as the original (39a4f67)
