urlutil: add a new `get_unique_push_path`
This function is dedicated to call that needs a single destination. Currently
most caller actually need that since few actually support multiple destinations
(the most importants `hg push` and `hg outgoing` do). So having a clear API
point for that will be important when the time comes to have a single `[paths]`
alias resolving to multiple urls.
