[nodejs,angular] stop adding local node_modules/.bin to path

Why
===
* We were having issues where our local node_modules bin had a "which"
binary that did not behave well.
* It isn't typical for local node_modules/.bin to be on the path, if
you want something on the path, you typically use npm install
--global, which is still added to the PATH after this change.

What changed
===
* Remove $REPL_HOME/node_modules/.bin from PATH

Test plan
===
* Check template tester still passes
* Check PATH does not contain that path in nodejs Repls
