Enable snippets_edit_vue by default

Updated the corresponding RSpec suits making sure the app works
with and without the flags:

- snippets_vue (vueified view of a snippet)
- snippets_edit_vue (vueifid edit form)

app/views/shared/snippets/_form.html.haml

-- if Feature.enabled?(:snippets_edit_vue)
+- if Feature.enabled?(:snippets_edit_vue, default_enabled: true)
   - available_visibility_levels = available_visibility_levels(@snippet)
   #js-snippet-edit.snippet-form{ data: {'project_path': @snippet.project&.full_path, 'snippet-gid': @snippet.new_record? ?
