Bug 1345109 - Delete 'JS_STANDALONE' from EmptyConfig when generating test metadata. r=mshal, a=test-only EmptyConfig objects set JS_STANDALONE=1 by default. However, test tasks that need to run without an objdir need to be behind an "if not CONFIG['JS_STANDALONE']" condition to avoid causing bustage to sm-pkg task (js packaging). This patch explicitly deletes that default value, only when generating the TestManifestBackend. Ideally, the js/src packaging should have their own moz.build instead of re-using the root moz.build. But this is an easier fix in the short term to get the marionette-harness tests working again. MozReview-Commit-ID: 26lHLY6WlZK
