pull: skip pulling remote bookmarks with bundle1 if a value already exist

For efficiency and consistency purpose, remote bookmarks, retrieved at the time
the pull command code is doing lookup, will be reused during the core pull
operation.

A first step toward this is to setup the logic avoiding pulling the data again
during the discovery phase if some have already been provided.
