WorkbenchSplicePlugin causes refreshes

[jc776]

The line override def requires = WorkbenchPlugin causes the 'refresh' plugin to load. It should be override def requires = WorkbenchBasePlugin.

scalaVersion in ThisBuild := "2.12.4"

val client = project.in(file("client"))
  .settings(
    name := "test-client"
  )
  .enablePlugins(ScalaJSPlugin, WorkbenchSplicePlugin)

workbench.js:121:160
Workbench connected
workbench.js:438:172

If I override that, it does load modified files without refreshing, but none of the 'modify methods while preserving state' behaviour works - I don't think any of the munge regexes work on the current fastOptJS.
