Fix clean.sh

tsc doesn't check if the output exists when incremental is true.

i.e if I delete the out directory, but keep the tsbuildinfo and
try to rebuild, nothing happens cause it thinks everything is
up to date I guess...

With this change, yarn clean will now remove the tsbuildinfo correctly
so things work as expected.
