tea pr checkout: fetch via ssh if available (#192)

Browse Source 
improved logging

try to use local branch before creating pulls/<PR>

useful for checking out your own PRs

reorder imports

refactor pulls checkout

isolated "gitea API to local git cfg" aspect

work around go-git limitation

As we cant manage multiple remote URLs properly, we just set the correct
URL protocol ahead of time.

This logic won't apply for already existing HTTPS remotes, these
should be deleted before using `tea pr checkout`.

use SSH if user has key in gitea
