Title: Fix table iterator issues

* incomplete results when performing the same query twice and exhausting
the second iterator before the first. (First one writes incomplete
results to _seqcache)
* False results potentially going to _seqcache if Row.update is used during
iteration.
* index wasn't being used if it claimed there were no results. Issue #351
