Suggest existing remote for non-tracking branch

Currently, when pushing or pulling a branch that has no tracking remote,
lazygit suggests the (hard-coded) remote named 'origin'. However, a
repository might not have a remote with this name, in which case the
suggestion makes no sense. This happens to me quite regularly when I
choose a more meaningful name than 'origin' for a remote.

This change keeps the current behavior by suggesting 'origin' when there
is either a remote with that name or no remote at all. However, when
'origin' does not exist, the name of the first remote is suggested.
