Fix Request Info for Catalog Items

[ZitaNemeckova]

Fixes https://bugzilla.redhat.com/show_bug.cgi?id=1584172

Data was never copied from session to @options when miq_request/prov_field_changed?tab_id=* request was fired

Services -> Catalogs -> Catalog Items -> choose any item with Request Info -> click Request Info -> click any tab in Request Info

Before:

Console:
