pull: Disable static deltas by default for local pulls

For local pulls there's no benefit pulling the static delta over the
individual object files since there's no HTTP overhead. Furthermore,
processing deltas always generates the objects whereas a standard pull
ensures that the exact object files are copied. Using deltas also
prevents hardlinking the objects if the repos exist on the same
filesystem.

Closes: #447

Closes: #448
