Cli does not prompt input with external default in interactive mode

| Customize Project

Project version (default: 1.0-SNAPSHOT): 

Switch directory to /Users/rgrecour/workspace/helidon-build-tools/cli/impl/quickstart-se to use CLI

This is because of the users config and its external defaults:

default.group.id=me.${user.name}-helidon
default.artifact.id=${init_archetype}-${init_flavor}
default.package.name=me.${user.name}.${init_flavor}.${init_archetype}
default.project.name=${init_archetype}-${init_flavor}
