This commit fixes unit tests for the following builds: 1. The no-deprecated build: `custom:-deprecated` 2. The current slim build: `custom:-ajax,-effects` 3. The future (#4553) slim build: `custom:-ajax,-callbacks,-deferred,-effects` It also adds separate Travis jobs for the no-deprecated & slim builds. Closes gh-4577
