Add feature spec to test if the 'Calculate winners'
button is enabled or not, depending on the phase.
It also checks the message that clarifies why the
button is disabled.
We were seeing this warning when running specs
`spec/features/admin/budgets_spec.rb:322: warning: circular argument
reference - phase_kind`
This commit should fix the warning
Why:
The Admin Budget form has a submit button for saving the record, adding
another submit input to destroy the record actually adds to the html:
`<input type="hidden" name="_method" value="delete">` and it collides
with the save button, forcing it to perform a destroy instead of save.
Previously the destroy button was not in the same div as the save button
How:
Just changing the Destroy from a button_to to a link_to.
