!!! BUGFIX: Make FluidAdaptor compatible with TYPO3Fluid 2.5.11+ and 2.6.10+

This is breaking in case you created your own ViewHelper that overrides the registerArgument() or overrideArgument() method. In that case you need to add a new boolean optional argument $escape = null and forward that to the parent method.

This is a backport of #2257 * Fixes: #2260 * Packages: FluidAdaptor

TASK: Use count instead of find in repository deleting resource 

This introduces a new function in the resourceRepository that allows to count the number of times a file is referenced in a PersistentResource.

Same change as with #2229 but should now be merged into Flow 5.3.
