Fix loadDrmInitData given DASH manifest parser changes

Browse source 
DASH manifests can now contain non-null but incomplete
DRM init data. Hence using the manifest init data when
non-null is not always the correct thing to do. This
change merges the sample and manifest formats (which
correctly merges the DRM init data) and then uses the
result.

Issue: #3630
