Subject: [PATCH] Resolve corpus promises 7503 and 7504 with an explicit
 undefined

tsgo checks JavaScript calls to an untyped Promise's resolve against its
one parameter, so resolve() with no argument is an error there while
tsc-ts accepts it. The two programs pass undefined, which both checkers
accept and which settles the promise the same way.
