Description

Trying to replace/accumulate a temp meta node on top of an existing one results in command failure because "Player already has temp meta".

Reproduction steps

1. Set a temporary meta node
2. Try setting it again on the same holder with accumulate as temporary modifier
3. It no work

Expected behaviour

I would expect it to:

• If using accumulate to add the time to the existing node
• If using replace to, well, replace the expiry time.

Environment details

• Server type/version: Paper running version 1.16.5 build 567
• LuckPerms version: v5.3.14

Any other relevant details

The command checks for existing nodes already (temp or not) before adding the new node, effectively ignoring the temporary modifier.
