Adding go.mod into node_modules is not sufficient, because npm install
wipes them quite often out. Similarly, when running npm install locally
it will remove it, causing the git state to be dirty.
Rather than having them committed, add them after running npm install.

Add timeout to npm install and increase logging level.
npm install is still taking sometimes too long and it's not clear why,
verbose logging is not sufficient.

The builds for npm still fail, however, `--timing` does not provide
sufficient data to debug the situation.
