After update: "Could not get code signature for running application"

[mitchhentges]

To reproduce:

1. Install the .dmg for 2.0.0-beta.1
2. Start James
3. Wait until "restart to update" text appears with green cloud
4. Click the "restart to update" text
5. James will restart
6. Upon loading, James will show "unable to update". Hovering over the error will show the message "Could not get code signature for running application".

• Restarting James again (command-Q, start James) makes the error go away, and the v2.0.0-beta.2 version is showed as expected

Note:
If, for step 4, you command-Q and restart James, James will behave properly. It's just when you click the "restart to update" text that it fails.

Acceptance criteria

• Clicking "restart to update" doesn't cause errors on OSX

I thought this error was a bit familiar... Turns out this is the same error that happened last time. 🤔
