Subject: [PATCH] Fix /sync may contain duplicate EDUs and EDUs for left rooms
 (#752)

In 29841be (#718), EDUs are added to /sync responses for rooms listed
in joinedRoomIDs returned by addPDUDeltaToResponse. However this list
may contain rooms other than those currently joined.

Some variable renamings are done to make golangci-lint pass.
