* scalafix ExplicitNonNullaryApply prepare + 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: ``` % sbt -Dakka.build.scalaVersion=2.13.1 > fixall ``` * scalafmtAll * Revert to ch.epfl.scala:sbt-scalafix Co-authored-by: Bùi Việt Thành <thanhbv@sandinh.net>
