Fix issue in ContentNeogitatingViewResolver

Browse Source 
The following commit in 3.2.3 had a side effect on CNVR:
aaded7e30b

It appears that CNVR doesn't treat a request for "*/*" differently
from a request that does not request content types. Both should be
interpreted as "any content type is acceptable". This fix ensures
that CNVR treats these two cases the same way.
