git-svn: allow dcommit for those who only fetch from SVM with useSvmProps

This allows users to use SVM (SVN::Mirror) to mirror a remote
repository to use dcommit to commit to the repository that SVM
was mirroring.  When dcommit is used in this manner, the automatic
fetch + rebase/reset does not happen; in which case the user will
have to manually invoke svm/svk, run 'git svn fetch', and finally
'git rebase'.
