fix ActivityStream button at details page

[aeter]

The current PR has the same fixes as this PR from the old user interface.

In short: at any "details" page (like, /access/organizations/1/details, /infrastructure/hosts/1/details, etc.) - if you click at the three dots at the top-right corner and choose View Activity Stream, it shows a generic activity stream for the category (organizations, hosts, etc.).

With the current PR, an __id parameter is added to the end of the Activity Stream query string, so the Activity Stream is filtered by host__id, orgranization__id, etc. - to the specific item.

Testing Done: tested locally

@aeter can you please push this pr directly to this repo instead of pushing it to a fork? Also, I want to call your attention to this pr which was just approved and provides some insight to the direction we are going with activity stream. #2706.

@AlexSCorey, @kialam : thank you very much! I was able to update the code, per the changed ActivityStream from the PR you linked.

As suggested, I tried to push a branch directly to the ansible-ui repo, but I don't have enough rights (I'm an external contributor, not from Red Hat).

So, I updated the current PR/branch, with my new code, and retested locally.
It can be merged without the need for github rights - if you think the code is ok.

This PR fixes/relates to this RedHat ticket

The code is probably not the best, but I'd be happy to improve it, if you have suggestions.
I answered the question regarding pushing to ansible/ansible-ui. To repeat, being an external contributor - I can open a PR only from my fork.
@kialam, @AlexSCorey - it seems there is some issue preventing us from moving forward with the code review and the fix.
