Jason Tedor 673754b1d5 Fix get source HEAD requests
Get source HEAD requests incorrectly return a content-length header of
0. This commit addresses this by removing the special handling for get
source HEAD requests, and just relying on the general mechanism that
exists for handling HEAD requests in the REST layer.
