Make sure to call the runtime trait functions (#1129)

* Make sure to call the runtime trait functions

The runtime trait functions export their functions as extern c
functions. These functions itself call the trait functions. This commit
makes sure that the trait functions are called and not functions with
the same name that are implemented for the runtime.

* Update the wasm files
