Subject: [PATCH] web: request the plan for a draft without creationExecutions
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The Platform API omits an empty creationExecutions array. generate() read
its length unguarded, so every never-executed draft threw before the plan
generation request and showed 計画を作れませんでした (APT-748, APT-749).
