FIX: grant first quote at the date post was created

Previously due to #b2dc65f9534ea date on the quoted_posts table could not
be trusted.

This changes it so we use the date on the actual post as the grant date.

Note: there is an edge case where you create a post and only add a quote
a week later. In this case the badge will not be awarded at the correct
time (it will display it was granted a week ago).
That said this is far more rare than the current situation.
