Make end-of-tour date inclusive

[pacodelcastillolopez]

The current de-activation of accounts based on end of tour date kicks before the end of the last day at work. This happens because the custom date picker used in the "Person" form rounds down the date to the start of the day. The new implementation will round up this date to the end of the day instead, so users are able to use ANET on their last day at the job.

Closes AB#1038
