Updated patch that sets estimate timestamp to null when we don't have
guideposts available for all regions.

Attachment: PHOENIX-4333_v1.patch
With this patch, we now detect that if we don't have stats information
available for all the regions, then we report estimates as null. The updated
test tests out this scenario.
[~jamestaylor], please review.

Attachment: PHOENIX-4333_test.patch
Test which demonstrates the issue that [~mujtabachohan] brought up. I would say
it is working fine. We call these estimates for a reason :). If the user
desires more accuracy, he/she should call UPDATE STATISTICS on the tenant view.
