[bug]: Crash on storage of user token with wasm

**Describe the bug 🐛**
Hive is not compatible with wasm and seems to be not maintained anymore. Maybe try with [hive_ce](https://pub.dev/packages/hive_ce) which is wasm compatible

I'm unable to locate the exact line that trigger the crash but I think it is insights.userToken = 'user-123';

**To Reproduce 🔍**
Try to use `insights.userToken = 'user-123';` in a project with `insights`, even without seting the userToken it should crash because I think it is the read that crashes.

On initialization it outputs this:
```shell

```

**Expected behavior 💭**
No crash

**Environment:**
algolia_insights: ^1.0.2

Build with `--wasm`

Start by reproducing the crash in a Flutter project using algolia_insights: ^1.0.2 and a --wasm build, focusing on the insights.userToken getter and setter. Trace the user-token storage path and check the reported Hive or hive_ce compatibility; done means reading or assigning the token no longer crashes under wasm.
