fix(ngit): pull and push find pr from branch

as since cl.get_branch_name has been introduced branch names
could be prefixed with a pr and sometimes postfixed with an event id

with the fix your branch could be called `article-editor`
or `pr/article-editor`
if you are logged in as the author of the PR (git config nostr.npub
matches the PR author)
or `article-editor(3fbba0ec)` which is what it would be named if you
weren't logged in as the author and checked out the branch on a
remote with the nostr url.
