Update EssentialsPlayerListener.java -> handlePlayerCommandPreprocess()

no need to recreate a HashMap instance to prevent concurrency since user.getCommandCooldowns() already makes a new HashMap  instance

the second if condition verifying entry.getValue() > System.currentTimeMillis() is redundant as it is already implied by the first if condition

Don't break in case there are other command cooldowns left to clear
