Fails to handle client-side editing paradigm since ObjectScript extension v3.0 #41
Description
Caused by intersystems-community/vscode-objectscript#1479
Identified by bisecting through releases. Failure first occurs with https://github.com/intersystems-community/vscode-objectscript/releases/tag/v2.12.11-beta.10
The client-paradigm workspace has no isfs-type folders, so our extension's attempt to use isfs uris to copy test classes to objectscript.conn-connected server's /.vscode/UnitTestRoot subtree fails.
