List references: transition from history to results is not smooth

[bpasero]

Steps to Reproduce:

1. have a history of references
2. find references again

=> 🐛 the transition from history to results is not very smooth, in the video you can see how the history partially still shows after running "Find References"

@sandy081 This is really cumbersome to implement with the tree. I think the message should be provided by the data source so that the "manual" sync step for extensions becomes obsolete. Then, I don't know of a good way to clear and populate the tree without it feeling sluggish...

Does it looks like a need for clear API that clears everything?

I group refresh calls now by waiting for some time. This could be causing the delay between message and refresh calls. May be I would try to group updating message and refreshes together and see how it behaves.

@sandy081 This is still pretty bad. I need the tree to refresh without showing the old nodes
