Remove redundant type_default variable

- `<%= select_tag(:action_type, options_for_select(action_type_arr, type_default)` was only being executed when `if condition.nil?` was true (now line 20). Additionally, that was the only line that was using the `type_default` variable.
  - Thus, no conditional is required for the assigning of `type_default` and we can just use `:remove` explicitly on line 30 now.
