Plugin redirects to inaccessible setup wizard when Posts Table Pro is active

[andykeith]

To reproduce:

• Activate Posts Table Pro
• Activate Posts Table with Search and Sort (first time activation)

The plugin attempts to redirect to the PTSS Setup Wizard, which cannot be accessed because Posts Table Pro is also active. Instead you see an error "You are not allowed to access this page". Can you prevent the redirect if PTP is installed?
