t9814: simplify convoluted check that command correctly errors out

This test uses a convoluted method to verify that "p4 help" errors
out when asked for help about an unknown command. In doing so, it
intentionally breaks the &&-chain. Simplify by employing the typical
"! command" idiom and a normal &&-chain instead.
