Revert "[BUGFIX] IMG_RESOURCE does not prepend absRefPrefix"

This reverts commit 23df34dc.
Due to this change in various instances the absRefPrefix was appended twice because of this commit.
If one wants to fix the issue one could modify
\TYPO3\CMS\Frontend\Controller\TypoScriptFrontendController::setAbsRefPrefix()
to also e.g. include single quotes.
