remotenames: synchronise remotenames after push also
Earlier we use to pull remotenames information from the server in case of pull
and clone only. This patch adds logic to push also command to pull remotenames
information.
This will help us in keeping the remotenames more upto date where there are a
lot people changing state of branches and bookmarks at the server.
