CREATE INDEX: do update index stats if autovacuum=off.

Browse Source 
This fixes a thinko from commit d611f8b15.  The intent was to prevent
updating the stats of the pre-existing heap if autovacuum is off,
but it also disabled updating the stats of the just-created index.
There is AFAICS no good reason to do the latter, since there could not
be any pre-existing stats to refrain from overwriting, and the zeroed
stats that are there to begin with are very unlikely to be useful.
Moreover, the change broke our cross-version upgrade tests again.
