Jan Provaznik 7f4452d406 Preload project features in reference parser
Preloading of project_features mitigates N+1 queries when checking
references in other projects.

When loading projects for resources referenced in comments it
makes sense to include also associated project_features because
in the following step (`can_read_reference?(user, projects[node],
node)`) project features is used for checking permissions for the given
project.
