Beemo v1.1.1 build failed

[cdmikechen]

I built project superset-ui in https://github.com/apache-superset/superset-ui with master version and it failed. I found that it use @superset-ui/build-config and @superset-ui/build-config use beemo.

{
    "@beemo/cli": "^1.0.6",
    "@beemo/core": "^1.0.8",
    "@beemo/driver-babel": "^1.0.6",
    "@beemo/driver-eslint": "^1.0.7",
    "@beemo/driver-jest": "^1.0.4",
    "@beemo/driver-prettier": "^1.0.4",
    "@beemo/driver-typescript": "^1.1.5"
}

I have open an issue apache-superset/superset-ui#265.
superset-ui github link is https://github.com/apache-superset/superset-ui .
Maybe someone can check what causes the Beemo failure.

@cdmikechen Seems like the issue is here: https://github.com/apache-superset/build-config/blob/master/configs/typescript.js#L24 Should be changed to String(context.workspaceRoot).

I probably made an accidental breaking change while adding windows support.
