don't refresh 'my' things when not logged in

Fixes #2094 - STR: make sure you're logged out, hit "new app" button. On dev: jquery errors because you're not logged in by trying to get `/my/` things. In this patch: no more jquery errors.
Just a nit, maybe merge this if return with the above?

```
if (!this.customcomponents || user.state === "signedout") {
  return;
}
```
