[Gutenberg] Ignore restore backup warning

[herrvigg]

While the post is edited with gutenberg, this warning appears after switching language:
"The backup of this post in your browser is different from the version below [Restore the backup]"

Until this is fixed the warning should be ignored - restoring the backup would overwrite the content with a different language (the previous one before switching language). This is particularly annoying when the post is first created before the initial publish.

Note the warning disappears when the post is published.

I realized this happens even when the post is published, not only in draft mode.
