Old version of nvm's Node.js in ~/.node_path

[alex7kom]

run-node caches the path with nvm version of Node.js that set as default when run-node first runs.
Right now run-node ignores a stale ~/.node_path only when node is not found, but there are other cases to consider:

1. A new version of Node.js was installed and set as default via nvm. run-node will continue to run the old version because the path in .node_path is not updated.

2. A new version of Node.js was installed and set as default via nvm, and the old version is deleted. run-node will not run the new version, and will run node found further in the path (like one installed via Homebrew).

Happy to consider solutions. I personally neither use nvm nor find it very good. I would recommend https://github.com/tj/n instead. It has no such problem.
