Form templates preview broken with tag group

I investigated and found that the reason is that the process tag group step is not executed. These two PRs should solve this problem.

The bare template yaml file provided by the user cannot be directly used for for…m templates preview, because components such as `TagChooserField` actually rely on a backend process step. This step exists when users actually use the template, but is missing when the admin writes and previews the template. This commit supplements the missing process step, thus fixing the problem that tag-chooser may break ember during admin preview

FIX: Check tag group names in form template validator

The previous form template validator did not detect non-existent tag group names…, which would result in the page being saved normally when an incorrect name was entered, but causing the interface to crash during preview and a 500 error to be thrown when the user used it. This commit adds detection for non-existent tag group names and fixes this issue
