bug: removing accounts does not remove them from thunderbird

Are you following the right branch?

• My Nixpkgs and Home Manager versions are in sync

Is there an existing issue for this?

Issue description

I start with enabling thunderbird with a single account like so:

programs.thunderbird = {
  enable = true;
     profiles = {
        default = {
           isDefault = true;
        };  
      };
   };
};

accounts.email = {
  accounts = {

      myemail = {
        primary = true;
        address = xxxxxxx";
        userName = "xxxxxxxxx";
        ....
        thunderbird.enable = true;
      };
   };
};

When I launch thunderbird I am able to see/use the "myemail" account.

If I change accounts to:

accounts.email = {
  accounts = {};
};

Thunderbird will still show that account, but it should not.

If I enable 3 accounts it will show the 3 accounts. Then if I remove all 3 from the configs, it will still show the 3. This makes me think that whatever config was defined before the accounts were removed will stay when the accounts are removed from the config. This should not be the case.
