Fix bug where Action UI may occasionally not load logs (#6122)

Browse source 
In the combination of events where the user is viewing an action that is completed (and therefore no interval-based loading of logs is occurring), and `loadJob` is called while `loadJob` is already running (commonly from expanding two log sections back-to-back), the second request for loading would be discarded and never occur.

To fix this, the invocation of `loadJob` keeps track of the log cursors it is attempting to load, and an aborted invocation stores its attempted load.  If `loadJob` succeeds in loading and finds that an attempt was aborted while it was busy, it will reload the data.

Steps to reproduce:
- Open an Action UI that is already "Done".
- Click on two steps in rapid succession to expand their logs.
- (Race condition) As long as the second click is registered while the first log chunk is being loaded, its data won't load.
