fix required: throw an error if build fails

[JohannesHoppe]

see angular-schule/angular-cli-ghpages#74

The deploy builder should stop the deploying process if the build breaks.

Broken:

ngx-deploy-npm/src/deploy/actions.ts

Line 41 in f93ab78

await build.result;

Fixed:

Please also note release v0.0.3 of npx-deploy-starter, where I made a number of small improvements. 😃
