Method handleGetProperties

valdi/src/valdi/hermes/HermesDebuggerConnection.cpp:209–225

Compatability workaround for debugging Hermes with Block Scoping enabled Issue outlined here: https://github.com/facebook/hermes/issues/1355. Should be fixed in a future release of Static Hermes. This workaround removes duplicate variables from the getProperties response so they display properly in the UI
