Channel details - The channel info is not getting updated correctly

[pcenov]

Observed behavior

When I remove some resources from my channel and publish it the resources' metadata and thumbnail remain visible on the channel info page. At the moment the info page is not getting updated even when I add new resources and publish the channel but at some point that seem to be working correctly.

Expected behavior

If I publish a channel after having removed or added resources the channel info page should be updated accordingly.

Steps to reproduce the issue

1. Open a channel
2. Select a resource and click the delete button
3. Publish the channel and go to the channel's info page

Not sure if some of this will be affected by #4113

There's some caching on the endpoint which returns this information. It is likely enqueuing a task to update it when it's loaded post-publish, but it returns the old cached data until that task is completed

[bjester]

We should update the publishing process to write theses details to a cache. The current approach relies on requests to the channel details API endpoint, to queue a task in order to update the cached details. This means that those details could reflect the current state of the channel and not the last published version's state. So proactively caching this information during publishing and retaining that cache until the next publish makes a lot of sense.

This issue needs to be re-written to clearly outline the needed change, as the issue is a consequence of the current implementation.
