Each node now has two index: nodeIndex and checkIndex.
nodeIndex is the index in both the view definition and the view data.
checkIndex is the index in in the update function (update directives and update
renderer).
While nodeIndex and checkIndex have the same value for now, having both of them
will allow changing the structure of view definition after compilation (ie for
runtime translations).
Throwing on query changes would be a breaking change compared to v2.
Also discovers a bug with querying manually projected content, see #15117.
