Raphaël Pinson 1ec72afe32 Do not alter pull_requests while iterating on it
Deleting elements of an array while iterating on it
results in never seeing the last element.

    > a = [1,2,3]
     => [1, 2, 3]
    > a.each do |e|
    >   p a
    >   a.delete(e)
    > end
    [1, 2, 3]
    [2, 3]
     => [2]
