Remove wasm-bindgen-test

Instead, tests are conducted by running a small js script which requires the
wasm module built from the test library. I removed wasm-bindgen-test because it
failed to link the test module when OsRand or StdRng::from_entropy were used,
despite the library working when required by js script.
