compileScoverageScala.outputs should include "scoverage.coverage"

[dsilvasc]

The scoverage instrumentation info file changed names from scoverage.coverage.xml to scoverage.coverage in scoverage/scalac-scoverage-plugin@4140954

The gradle plugin still only models the old filename in

gradle-scoverage/src/main/groovy/org/scoverage/ScoveragePlugin.groovy

Line 201 in c5870c9

outputs.file(new File(extension.dataDir.get(), 'scoverage.coverage.xml'))
