- was throwing an error when trying to update commentsCount because of new implementation by @roschaefer which uses countResolver, but there was no related for commentsCount, it was r... also commentsCount is no longer needed anywhere in the code base, it is commentedCount now
- add filtered state to vuex, so as to maintain filter
