npm rebuild --runtime=electron --target=1.3.4 --disturl=https://atom.io/download/atom-shell --abi=50

in your case it should be 49

This is well-know problem when when upgrading node version. For example: you are using Node for example version 5. You add some libraries inside your project, build and run that. All your libraries will be compiled under node version 5.

And then you upgrade your node for example to version 6. And then you run some commands that using node, for example npm run test. The problem is here: you use newer node version for running libraries that compiled by older node.

Solving this is easy by 2 following commands:

rm -rf node_modules // force remove node_modules directory
npm install         // install again all libraries. Libraries will be compiled again with node version 6

So this is a general method apply for all javascript frameworks, not only electron ...

Since mdns contains a native Node module you must rebuild it to target your version of Electron, there are a couple of ways to do this. I'd suggest using the electron-rebuild approach.
