manifest_xml: fix url normalization for inits and remotes

Before the change, repo normalizes the urls
with a following format only:

    git@github.com:foo/bar

It doesn't cover the following case:

   <remote name="org" fetch="git@github.com:org/" />
   <project name="somerepo" remote="org" />

Results to:
   error: Cannot fetch somerepo
     from ssh://git@github.com/org/git@github.com:org/somerepo

Current change fixes it by normalizing this format:

    git@github.com:foo

Test: ./run_tests tests/test_manifest_xml.py
