Crash on transferring time from the offer's page

[sauloperez]

Looks like we're missing one parameter from the payment button on the offer page.

It should be https://www.timeoverflow.org/transfers/new?destination_account_id=22&id=6&offer=12597
and from the button, we link to https://www.timeoverflow.org/transfers/new?id=6&offer=12597. This happens when clicking on the top-right green button on an offer's page.
