[BUGFIX] Use correct typoscript settings in ClickEnlargeViewHelper

The ClickEnlargeViewHelper receives typoscript settings in the extbase
format without the leading dots. The code called by the viewHelper
expects the typoscript syntax with the leadings dots.

This patch converts the settings array to a TypoScript array before
passing the settings to imageLinkWrap().
