Remove peerDependencies and peerDependenciesMeta

@mshima not sure, WDYT?

This is on purpose to don’t allow blueprints to use another yeoman-test version that isn’t compatible with JHipster.
yeoman-test is a jhipster devDependency so it’s not installed by default.
Blueprints should add yeoman-test in devDependency but should be a version compatible with current generator-jhipster.
By having a broader yeoman-test in blueprint package.json, generator-jhipster peer dependency will limit to that version.
