fix: Call resolve in the close callback

[gribnoysup]

Okay, so the real fix is this one line in the close callback handling, but then tests started failing for me with

Error: Debug Failure. False expression: Non-string value passed to `ts.resolveTypeReferenceDirective`, likely by a wrapping package working with an outdated `resolveTypeReferenceDirectives` signature. This is probably not a problem in TS itself.

coming from ts-node and only updating all TS deps fixed it, hope that's fine
