Remove workaround to ship legacy clasp package in webtools tests

[dibarbet]

In #10139, code was added to ship the legacy clasp package along with the webtools dependencies in the Razor tests. Once webtools updates to the source package version of clasp in https://devdiv.visualstudio.com/DevDiv/_git/WebTools/pullrequest/538001, Razor should update to those packages and remove the workaround

Can this be actioned now?

As luck would have it, I needed to move some code around today and this workaround bugged me, so I'll fix this :)
