Fix all scripts that run w/bedrock to be consistent and properly run npm install in root dir

[dlongley]

Eliminate style inconsistencies in run: | vs. multiple runs and so on. Make it all consistent so it's easy to copy and know what to do.

For libs like bedrock*, do not rely on test package.json incidentally installing deps that the root package needs, run npm install properly before going into test and running npm install there. Fix usage across all packages.
