Add Margin to Resend Confirmation Form

I fixed this issue on the "Reset Password"-form (https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/20), but found it is also occuring on the "Resend Confirmation"-form. There currently is no margin between the input (email-address) and button. This commit is a simple fix.
