Do not attempt to jump in the air or pathfind while elytra is active

## Describe your suggestion
Baritone glitches out while elytra is equipped due to it sometimes attempting to jump while in the air. When the elytra gets activated, it glitches out again and sometimes leads to deaths.

## Settings
None

## Context
It makes sense that since Baritone doesn't support flight/elytra, it shouldn't attempt to use it even accidentally.

## Final checklist
- [x] I know how to properly use check boxes
- [x] I have not used any OwO's or UwU's in this issue.
