Bug 25139: Corrections to date picker handling

Bug 25139: Corrections to date picker handling

It would appear one has to format the dates in the controller rather
than in the template for input fields.. I wasn't aware of this caveat
until now.

Test plan
1/ Prior to applying patch attempt to look at previous transactions
ensuring you enter a 'to' date.
2/ Note a catastrophic failure
3/ Apply patch
4/ Look at the same date range and note you no longer get a failure but
are instead faced with the requested transactions.
5/ Signoff
