Refactor: redirection of IO in EntryPoint

[danglotb]

It looks like there is a clash between the management of the redirection of the IO

test-runner/src/main/java/eu/stamp_project/testrunner/EntryPoint.java

Lines 750 to 769 in adb1c99

	if (EntryPoint.verbose) {
	// Redirecting to given output stream
	if (EntryPoint.outPrintStream != null) {
	pb.redirectOutput(Redirect.PIPE);
	pb.redirectError(Redirect.PIPE);
	} else {
	// Redirecting to main process IO (System out/err)
	pb.inheritIO();
	}
	} else {
	// Redirecting to null file is required to avoid thread deadlocks (when verbose
	// is disabled)
	pb.redirectOutput(File.createTempFile("test-runner-error", ".tmp"))
	.redirectErrorStream(true);
	}
	process = pb.start();
	if (EntryPoint.verbose && EntryPoint.outPrintStream != null) {
	inheritIO(process.getInputStream(), EntryPoint.outPrintStream);
	inheritIO(process.getErrorStream(), EntryPoint.outPrintStream);
	}

The condition EntryPoint.verbose && EntryPoint.outPrintStream != null is checked twice and has two different bodies.

pb.redirectOutput(Redirect.PIPE);
pb.redirectError(Redirect.PIPE);

vs

inheritIO(process.getInputStream(), EntryPoint.outPrintStream); 
inheritIO(process.getErrorStream(), EntryPoint.outPrintStream);
