Fix conflicting dependencies

[davidyuk]

When the last time I updated dependencies, probably I was using an outdated version of npm that didn't warn me about conflicting dependencies like eslint and rxjs.

Downgrading the conflicting dependencies is not an option because they seem to work now. Ideally would be to update other dependencies like @vue/cli-plugin-eslint and vue-rx (looks unmaintained).

As a workaround npm install --force should be used, or npm_config_force=true npx cordova prepare ios.
