Update web push dependency 3.3.2 to 3.4.4

[bartbutenaers]

Hi @webmaxru,

This pull request updates the web-push dependency from version 3.3.2 to version 3.4.4, to solve this issue. Which is important because otherwise we create conflicts for the migrated http-request node starting from Node-RED 2.0?

Via the npm list command, you can now see that we have the required agent-base version:

There have been a lot of intermediate releases between web-push version 3.3.2 and 3.4.4, but almost all commits were related to updating versions of dependencies. Only following commits have added new features:

1) commit allows a http agent to be specified in the https.request method. But since you also don't allow a proxy to be specified in the options, I don't see any reason at the moment to add the agent option.

2) commit a timeout to be specified (in milliseconds). On timeout of the https.request, the request will be destroyed and the promise will be rejected with a meaningful error. Since that might be useful, I have added that to your configuration node:

By default (and for older nodes) this timeout is 0, which means that I don't pass it in the options.

Some remarks:

• I have added a ^ in front of the web-push version number, to make sure minor releases of that dependency are automatically installed, as soon as users (re)install your node.
• I have removed a duplicate code snippet in the config node.

So no major changes. Your node now still works fine in my setup...

Thanks for reviewing!! Bart
