Report Widgets Core: Add method to load collapsed data
Problem to solve
For &7066 (closed) we need to be able to call the fetchCollapsedData
method again to retry when the fetch failed.
Currently the collapsed data is loaded in the mounted
lifecycle method.
Suggested solution
Create a component method for loading the collapsed data that can be called by consumers.
This method should also set the loading state.
