Change the way totalNotes is calculated

totalNotes is only used to prerender a number of
skeleton containers until real notes are loaded

issuable.discussions makes multiple requests, so
too expensive for this

This commit uses mere notes for this and sends
actual totalNotes number if it's less than 10;
otherwise it sends 10 - it allows us to avoid
bunch of skeleton prerenderings, which are not
necessary since they doesn't fit into the whole
screen and disappear quite fast
