Send skillId when creating TaaS project

[jmgasper]

@suppermancool - In dc0438e, we changed to use the new skills stuff, but we're sending a different value for each skill when we create the project, sending name, value, and label, instead of skillId and name. We need to ensure we keep sending skillId and name instead, since those are used in various places after the user has confirmed the skills, and when creating the jobs in the backend.

@jmgasper based on your recent update in d6a780c the frontend is sending name, value, label, skillId

In this patch, I removed value, label field and fixed some skills UI issues:
