There are two problems in enabling Travis builds of an Electron snap: 1) snapcraft enable-ci travis will blow up if it cannot find a snapcraft.yaml. The snapcraft.yaml file is created by electron-builder during an npm run and never retained. 2) Electron projects cannot be built by calling `snapcraft`. They must be built using `npm run dist` (or some other package.json script stanza). snapcraft enable-ci travis puts `snapcraft && snapcraft push *.snap --release edge` in the .travis.yml, which will not work.
