[FIX] generateResourcesJson: Make resources.json generation deterministic

Stop analyzing debug-resources if they correspond to a non-debug
resource.

Only analyze the non-debug resource and copy any dependency information
to the corresponding debug-resource.

While this might not be the best approach given that analyzing the
source ("debug") version of a resource might result in finding more
dependencies (i.e. those mangled during minification), this change
ensures that we generate the same resources.json, independently
from the order of debug and non-debug resources supplied to the
resourceListCreator processor.
