Prefer internal version + improve handling of local dev builds
This commit does the following: - Ensures that the Chrome Web Store version is disabled instead of the internal version when duplicates are present. To do this we also rely on the stable ID of the internal version - It improves handling of local dev builds: - For dev builds, we enable the "management" permissions, so dev builds can easily detect duplicate extensions. - When a duplicate extension is detected, we disable the dev build and show an error so that other extensions are disabled or uninstalled. Ideally in this case we would disable any other extensions except the development one. However, since we don't have a stable extension ID for dev builds, doing so would require for other installations to wait for a message from this extension, which would unnecessarily delay initialization of those extensions.
