Creates Gmail account twice if no previous state could be loaded

[Niklas Wenzel]

How to reproduce:

Run the following commands:

stop account-polld
stop ubuntu-push-client
rm ~/.local/share/account-polld/*

What happens:

account-polld initiates each account twice as soon as it recognizes it cannot load a plugin's state from the storage:
