IfElseRuntime incorrect behaviour

**Describe the bug**
`FridaRuntime`s used in `IfElseRuntime` do not work correctly. This breaks ASAN in the `frida_libpng` example fuzzer for example.

**To Reproduce**
Either simply run the `frida_libpng` example fuzzer and observe that ASAN is not working correctly, or:

1. Create a fuzzer with `asan` in the `runtimes` for `FridaInstrumentationHelper`
2. Verify that ASAN is enabled and working
3. Replace `asan` with `IfElseRuntime::new(move || Ok(true), tuple_list!(asan), tuple_list!())`
4. Observe that ASAN is no longer working

**Expected behavior**
`IfElseRuntime::new(move || Ok(true), tuple_list!(asan), tuple_list!())` should behave identically to `asan`.
