Adds dependency declarations to order tasks (#237)

The missing dependency declarations result in errors in the release
tasks - pointing to possibility of incorrect result depending on order
in which these tasks execute.
The release tasks are skipped during normal :build jobs so build passes,
but the artifacts snapshot generation for release fails.
