>ccls: Call Hierarchy broken on VSCode 1.47.1

[Noh3choo]

Observed behavior

With a function symbol selected, running the command pallet command ccls: Call Hierarchy will display call hierarchy of the function. Any further attempts to the use ccls: Call Hierarchy fail to update the call hierarchy pane.

Expected behavior

Call Hierarchy pane to be updated.

Steps to reproduce

1. Run command ccls: Call Hierarchy
2. Run it again

I've experienced the same problem with VSCode 1.48.2 and version 0.1.29 of the plugin. Downgrading the plugin to 0.1.28 solves the call-hierarchy issue, but not sure if it exposes some other problems.

that seems to be a duplicate of #102 .
