Live Share collaboration not working on VSCode

[rasavant-ms]

Issue Type: Bug

VS Live Share does not let collaborators debug and does not let me change settings to enable this. This is the error message seen - Unable to write to Workspace Settings because liveshare.allowGuestTaskControl is not a registered configuration.

VS Code version: Code 1.39.1 (88f15d17dca836346e787762685a40bb5cce75a8, 2019-10-10T23:31:28.683Z) OS version: Windows_NT x64 10.0.17763
