Error cleaning target folder when is the root folder

I'm getting this error when target folder is the SPO Library root and set cleanTargetFolder to true:

`Cleaning target folder '/'. { Error: Resource not found for the segment 'root:'. at new GraphError (/home/vsts/work/_tasks/az-pipelines-2-sharepoint_1ed28650-ea93-45a3-8f29-d0400ad51ce9/0.3.4/node_modules/@microsoft/microsoft-graph-client/lib/src/GraphError.js:34:28)

I was able to reproduce the error in Graph Explorer when the path-based address is malformed /root:/:/children and to work i have to change to /root://:/children

Maybe this function constructFileUrl needs a condition when receiving the root of a library or drive ("/") as target folder.
