Run more tests in wasm

Instead of repeating ourselves in defining one big test for the wasm
target, we can override the `test` attribute with the `wasm-bindgen-test`
one and therefore automatically run all (supported) tests in wasm.

Unfortunately, wasm doesn't support catching panics yet which means we
have to disable the `test_panic_raw_ctx` test.
