WSOD by changing name of section and if Fluid caches are generated
If you change the name of some section in your Layout and caches were generated before this change, then you get WSOD with following message in php log file:
PHP Fatal error: Call to undefined method FluidCache_Vendor_PackageName_Standard_action_index_bb47a7064d2c509f0bd5f35af56ae64023f35f04::section_3065c96e28893f22b707315d76eb3c0794993450() in ...../Packages/Framework/TYPO3.Fluid/Classes/TYPO3/Fluid/View/AbstractTemplateView.php on line 247
as you can see Fluid tries to call section_3065c96e28893f22b707315d76eb3c0794993450() [also 'section_' . sha1($sectionName)]
Fluid makes no checking if layout file was changed and no check if method exists.
Fluid should throw an exception on this place instead of WSOD.
