fix: swap runtime disposal ordering in asyncify variant

[hectorm]

While upgrading to 0.32.0 I ran into this error when host functions (created via newFunction()) were still referenced at teardown:

QuickJSRuntime(rt = 5333456) not found when trying to free HostRef(id = -2147483648)

After digging into it, the cause is that module-asyncify.ts calls deleteRuntime() before QTS_FreeRuntime(), so by the time GC runs the host_ref_finalizer for HostRef objects, the runtime's callbacks are already gone from the map.

I just copied into module-asyncify.ts the same changes made to module.ts in #227 (reference).
