Ben L. Titzer 15925e5cc6 [wasm] Fix import of reexported API function 
When a function is exported from a WebAssembly module, it is implicitly
wrapped in a WasmExportedFunction. For functions that were imports into
this module, the exported function appears like other Wasm function,
e.g. can be used in tables. When that exported function was re-imported
to another module, the logic to compute the import kind mistakenly
assumed the exported function was indeed originally a Wasm function
and tried to call it directly, instead of treating it like an imported
JS function.
