Calculating winners before the balloting is over is useless (results
aren't published at that point) and can lead to the wrong results since
users are still voting and results might change.
And we were showing the button to calculate winners even when a budget
had finished. However, in this case the action to calculate winners did
nothing, which resulted in administrators seeing nothing happened after
pressing the button.
Having links in the middle of a form distracts users from the task of
filling in the form, and following a link before submitting the form
will mean whatever has been filled in is lost.
And the budgets form is already very long and hard to fill in. Having
the phases table in the middle of it made it even harder. And, since
we're planning to add the option to manage groups and headings from the
same page, it's better to have a dedicated page for the form.
