Disable fly for /togglerank

[sly jay]

So there have been several instances of me getting hackusated because I have been flying around the lobby either by /fly or /elytra without a rank. I feel like these commands should be disabled if you have your rank hidden to prevent any unnecessary reports

[rough bone]

ah yes I hacked this elytra in

Indeed

Ive been accused of this 5 times in an hour ;-;
