Adding log details even when the log has only media.

[Rakshas7]

Added log.getDetails() to test log when the condition log.hasMedia() is satisfied. This will add log details to extent report when only the screenshot is appended to a log.

I started working on this, but just realized that the latest master already has this built-in, see below:

    private void constructLog(final Log log, final ExtentTest extentTest, final ExceptionInfo ex) {
        final Media m = log.getMedia();

        if (m != null) {
            if (m.getPath() != null) {
                extentTest.log(log.getStatus(),
                        MediaEntityBuilder.createScreenCaptureFromPath(m.getPath()).build());
            }
            if (((ScreenCapture) m).getBase64() != null) {
                extentTest.log(log.getStatus(),
                        MediaEntityBuilder.createScreenCaptureFromBase64String(((ScreenCapture) m).getBase64()).build());
            }
        }

        if (ex != null) {
            if (!extentTest.getModel().hasLog()) {
                extentTest.log(log.getStatus(), log.getDetails());
            }

            final List<Log> logs = extentTest.getModel().getLogs();
            final Log lastLog = logs.get(logs.size() - 1);
            lastLog.setException(ex);
            extentTest.getModel().getExceptions().add(ex);
        }
    }

Thanks for your efforts. :)
