Fix PDF and full-screen links for dashboard widgets

[mzazrivec]

1. Go to Cloud Intel -> Dashboard
2. for each and every widget present, try do download its PDF report (if possible). Correct report should be rendered, no error should occur.
3. for each and every widget present, try to go full screen (if possible). Correct report should be rendered, no error should occur.

for rr_id=... we need to correctly pass the report result id, not the widget id.

LGTM, tested in the UI...

I still get 2 exceptions here (as opposed to 5 before), but now the opened reports actually match the right graph 👍

(I'm guessing the remaining exceptions have to do with the result having been generated before the changes that would make miq_group_id non-NULL - either that or a second bug.)

(Also I notice that fullscreen reports now seem to be using the login layout, not application, for some reason.)
