svnsubrepo: check if subrepo is missing when checking dirty state (issue5657)

During an hg convert command, subrepos are not checked out. However, a
manifestmerge may occur during an hg convert if there is a merge
commit, which in particular will check the dirty state of subrepos.
Before this change, the lack of a checked out subrepo would error out.

This check for svn subrepos is modelled after 2fdea636f254 for git
subrepos.
