[BUGFIX] Fix wrong action call if CE is loaded in content elements
If a content element, like the youtube or spotify element, is added
to the inline content elements of another extension, e.g. ext:news,
TYPO3 looks after templates of the current controller action, which
is e.g. News->detail. If the CE has not defined its own controller
action, TYPO3 takes the controller name of the parent extension
(news) and can not resolve Detail.html within ext:supi.
This bugfix just adds the missing configuration
extbase.controllerActionName to the according CEs so TYPO3 resolves
the correct template path.
Resolves: #40
