Some changes for Phoenixx

See merge request !143

RPC Module

See merge request !142

Modify wasm_tests to use our local wasm_exec file instead of the systems. We should not need to do this but there is a dependency somewhere forcing older 'go' module and that is causing an error when instantiating webasm in the tests.

npm package config

Remove the workers in jsutils in favor of functions in src/workers.js, modify the paths to load blob urls of the workers

There are parts from webpack we don't control which start with a /, so we'll go with making sure all our paths prepend a / instead.

This reverts commit ce7da9b2.
