ui: support paths.default-push without paths.default set (issue4914)

This behavior regressed as part of the paths API refactoring. Previous
behavior was to accept "default-push" without "default" defined. Current
behavior aborts with "default repository not configured!." This patch
restores the old behavior and adds test coverage for the scenario, which
was absent before.
