Pass correct api.Module to host functions (#1213)

Browse Source 
Fixes #1211

Previously, host functions are getting api.Module for the "originating" module, 
which is the module for api.Function currently invoked, except that the api.Module 
is modified by withMemory with the caller's memory instance, therefore there 
haven't been no problem for most cases. The only issues were the methods 
besides Memory() of api.Module, and this commit fixes them.
