Cannot inject reactive Pool/PgPool into gRPC Singleton
**Describe the bug**
A null reference is passed while injecting a reactive `Pool` or `PgPool` into any bean annotated with `@Singleton` if extension `quarkus-grpc` is added. Injection of my own Singleton works fine.

This mostly affects injection into a gRPC service implementation as these services only work if annotated with `@Singleton`. Injection into `@ApplicationScoped` keeps working as expected. Injection fails with `@Dependent` as well. I did not try any other.

Injection of an `@ApplicationScoped` bean into `@Singleton` still works, probably since its a Proxy. My understanding is `PgPool` is supposed to be a `Singleton` itself, so there shouldn't be a reason to not be able to inject it into a Singleton.

Injection of `PgPool` into Singleton/Dependent works fine in a regular REST project without `quarkus-grpc`.

Tried the following injection methods:
1. package-private field annotated with `@Inject`
2. constructor with `@Inject`
3. constructor without `@Inject`

**Expected behavior**
We should be able to inject reactive Pool/PgPool in gRPC Singletons.

**Actual behavior**
In a gRPC Singleton, injected Pool/PgPool is null at both construction and runtime.


**To Reproduce**
Steps to reproduce the behavior:
1. Create gRPC service with `quarkus-grpc`, `quarkus-reactive-pg-client`, `quarkus-resteasy`, , `quarkus-resteasy-jackson`, `quarkus-resteasy-mutiny`
2. Add `@Inject Pool pool` to the `@Singleton` extending a gRPC service.
4. In one of the service methods add a Null-Check on `pool` and return an error on null.
3. Launch quarkus
4. Test the method to confirm null.

**Configuration**
```properties
quarkus.datasource.db-kind=postgresql
quarkus.datasource.username=test
quarkus.datasource.password=test
quarkus.datasource.reactive.url=postgresql://localhost:5432/test
```
