+ Temporarily use com.sandinh:sbt-scalafix because scalacenter/scalafix#1098
+ Add ExplicitNonNullaryApply rule to .scalafix.conf
+ Manually fix a NonNullaryApply case in DeathWatchSpec that cause
`fixall` fail because ExplicitNonNullaryApply rule incorrectly rewrite
`context unbecome` to `context unbecome()` instead of `context.unbecome()`
* scalafix ExplicitNonNullaryApply
fix by enabling only ExplicitNonNullaryApply rule in .scalafix.conf then:
```
