eolian_mono: fix to support event info which is a type defined in eo

Summary:
Previously, if event info was not structure and it was a type defined in
eo, then the type value was not passed to the event info correctly.

e.g. if event info was Efl.Ui.AlertPopupButton enum type, then
     default(Efl.Ui.AlertPopupButton) was always passed to event info.

Now, the given type value is passed to the event info correctly.
