Fixed: Missing file results in error

(OFBIZ-9198)

When accessing a file/image in ecomseo (only seo version) that is physically 
missing or the dataresource attribute isPublic=="N" the request results 
in a loop.

jleroux: to break the loop in case or error, I simply decided to return a 
response of type none. I also added the same for io-error which can be returned
by the DataEvents class, also in ecommerce controller

Thanks: Ingo Wolfmayr for report
