Fixes broken audits

* Went into Comment branch before checking if any audit attributes changed.
* Fixes date picker for ready to adopt field (thought I did this already, buh?)
* Fixes model spec
datepicker for ready to adopt is needed in two spots.  When an adopter is creating an application and when a staff member updates the attribute.  We were overwriting each others changes
