superproject: Don't update the commit ids of projects if remote is different.

1) Skip setting the revision id (commit id) for the projects whose
   remote doesn't match superproject's remote.
2) exp-superproject/superproject_override.xml includes local_manfiest's
   projects. When we load this XML, don't reload projects from local.xml
   (otherwise we will get duplicate projects errors).

Tested the code with the following commands.

$ ./run_tests -v

+ Test with local.xml
  $ repo_dev init -u sso://android.git.corp.google.com/platform/manifest -b master --use-superproject --partial-clone --clone-filter=blob:limit=10M && mkdir -p .repo/local_manifests && (gcertstatus -quiet=true || gcert) && ln -s /google/src/head/depot/google3/wireless/android/build_tools/aosp/manifests/mirror-aosp-master-with-vendor/local.xml  .repo/local_manifests/local.xml

  $ repo_dev sync -c -j8

+ Test without local.xml
  $ repo_dev init -u sso://android.git.corp.google.com/platform/manifest -b master --partial-clone --clone-filter=blob:limit=10M --repo-rev=main --use-superproject
  $ repo_dev sync -c -j8
