Description

The command used to check a permission node of a group returns false information.
If the node is not defined, it will return undefined as it should, however if the node is defined and its value is false, the command will still return that the permission node is set to true regardless.

Steps to Reproduce

1. Set up a clean installation of Spigot (Paper 1.16.1 was used for testing) with only LuckPerms.
2. Add any permission node to the default group. (here, we'll use example.example) and set its value to false:

/lp group default permission set example.example false

3. Query the value of the permission node you created using the command:

/lp group default permission check example.example

Expected Output

Notice how it says that the node is set to false, as it should be.

[LP] default has permission example.example set to false in context global.

Actual Output

Notice how it says that the node is set to true, despite us clearly declaring its state.

[LP] default has permission example.example set to true in context global.

It was suggested that I add this screenshot to this issue.
