BUG - ItemMatcher no longer works in MM 5.9.0 Release

Summary

When using itemMatcher as per the wiki, they are not recognized in the - holding{m=<MATERIAL or internal mythic item name>}

Steps to reproduce

1. Start server with MythicMobs version 5.9.0 Release or 5.9.1 Dev Build 5444
2. Create the following files:
   • Item file: https://paste.helpch.at/abuyiroxah.less
   • Mob file: https://paste.helpch.at/ogogubibeb.yaml
   • Skill file: https://paste.helpch.at/fogesosatu.yaml
3. Spawn the test mob with /mm m s wolfe_testmob
4. Interact with the mob holding the following items
   • /mm items get wolfe1_mythicitem
   • PAPER
   • /mm items get wolfe2_mythicitem
   • DIRT

Current behaviour

• wolfe1_mythicitem, "Wolfe's Mythic Ink", results = nothing happens
• PAPER, results = nothing happens
• wolfe2_mythicitem, "Wolfe's Mythic Stone", results = "<caster.name>&f<&co> This is the Mythic item I am looking for, oink!" message
• DIRT, results = "<caster.name>&f<&co> This is the Vanilla item I am looking for, oink!" message

There were no errors in logs. But I believe this is related to:

• https://git.mythiccraft.io/mythiccraft/MythicMobs/-/issues/1875
• https://git.mythiccraft.io/mythiccraft/MythicMobs/-/issues/1821

There are no more errors, but functionality is still missing.

Here's a video of the current behaviour: https://youtu.be/dkgLgjJGVqc

Intended correct behaviour

All four messages should output correctly with the required item.

Note: Even using the PA* in itemmatcher to catch the PAPER material didn't work.

Debug log snippet

NONE provided. If you want I can redo the test in a more isolated environment to provide these.

Proposed fixes
