Getting some weird behaviors when in a repo with multiple remotes. But I think it's not due to the changes in this PR, but rather with the way getHostingServiceMgr is implemented.

Copy branch url seems to only use the base url of the upstream named origin. This results in a 404 if the upstream named origin does not have a branch with that name.

Maybe we can find a way to pass in the name of the upstream of the branch we want to get the url / open a pull request for? We can always default to origin.

Especially since this is already what we are doing in CheckRemoteBranchExists.

Valid point @karimkhaleel. I'm not sure how we'd deal with upstreams (for from and to branches) when creating pull requests given that lazygit has a pull request options menu where the target branch can be selected. The branch URL part is clear to me.

Maybe we just leave the to branch as default, like the first option in the View pull request options... menu? This is already what the lowercase o keybind does in the branches menu anyway.
