Always log Browser's console messages/errors on failed test

[mreiche]

Implement reading console log messages that comes from the browser when a test failed.

Proposal

public List<String> getJavaScriptLog() {
    List<String> list = new LinkedList<>();
    LogEntries logEntries = this.getWebDriver().manage().logs().get(LogType.BROWSER);
    for (LogEntry entry : logEntries) {
        list.add(new Date(entry.getTimestamp()) + " " + entry.getLevel() + " " + entry.getMessage());
    }
    return list;
}
