Indexed queries need to translate between view table paging state
and base table paging state, in order to be able to page the results
correctly. One of the stages of this translation is overwriting
the paging state obtained from the base query, in order to return
view paging state to the user, so it can be used for fetching next
pages. Unfortunately, in the original implementation the paging
state was overwritten only if more pages were available,
while if 'remaining' pages were equal to 0, nothing was done.
This is not enough, because the paging state of the base query
needs to be overwritten unconditionally - otherwise a guard paging state
value of 'remaining == 0' is returned back to the client along with
'has_more_pages = true', which will result in an infinite loop.
This patch correctly overwrites the base paging state unconditionally.
