Temporarily disable clippy unused_unit test

wasm-bindgen 0.2.79 introduced a change in code generation that makes clippy complain
A fix has already been merged to main (rustwasm/wasm-bindgen#2778)
but we have to wait for the next official release to make use of it.
Once we update to the new wasm-bindgen with the fix we should remove
this workaround!
