Fix multiple-value uuid.NewV4() in single-value context

Thank you! a couple of things I noticed:

• Please update the .travis.yml file so that the deploy triggers on 1.10.x instead of 1.8.1 (it would never trigger otherwise)
• Please change the code so that instead of generating model.ID, _ = uuid.NewV4() it generates model.ID = uuid.Must(uuid.NewV4()) to maintain the same behavior.

I think https://github.com/goadesign/gorma/pull/166/commits/6191fee5dd9447600311d7ee154b089f7269db53#diff-354f30a63fb0907d4ad57269548329e3R34 needs to be 1.10.x or at least 1.10.2 since that's the last Go version and what 1.10.x will target when Travis builds.

Great, thank you!
