Report: "Manual restart required on accepting first invite w/ folder"

An anonymous tester reports:

It is necessary to manually restart after accepting an initial invite in order to see the remote folders.

Steps to reproduce

  1. Install Gridsync completely fresh
  2. On another machine, create an invite code containing at least one folder
  3. On the initial machine, open Gridsync for the first time and accept that invite

What is the current behavior?
Grid shows as connected, but no remote folder(s) appear(s) until either adding a local folder or quitting and reopening Gridsync.
