Even though I marked this thread here SOLVED I'm creating this here as another possibility as I don't see AkonadiTray yet being ported over and thought there has to be a better way. So, the below code can be copied to a file saved as something like "Stop_Akonadi". Remember where that is saved and be sure it is set to "Is Executable". Go System Settings --> Startup and Shutdown. From here click add script. Locate the file just saved/set and click OK. Now every time you log in, after the wait period Akonadi will be shut off. I'm sure that is how AkonadiTray worked to some extent.
Code:
#!/bin/bash sleep 25s akonadictl stop
