@MongoEntity with database parameter does not detect database when using mongo panache

[romilpunetha]

Describe the bug

The following is my code structure:

public interface BaseMongoRepository<T extends BaseMongoEntity>
         extends ReactivePanacheMongoRepository<T>  {}

public interface UserRepository 
        extends BaseMongoRepository<UserEntity> {}

public class BaseMongoRepositoryImpl<T extends BaseMongoEntity> 
        implements BaseMongoRepository<T> {}

public class UserRepositoryImpl
        extends BaseMongoRepositoryImpl<UserEntity>
        implements UserRepository

@MongoEntity(database = "userDB", collection= "users")
public class User {}

When I'm running this code, mongo panache fails with IllegalArgumentException:

The database attribute was not set for the @MongoEntity annotation and neither was the database property configured for the default Mongo Client (via 'quarkus.mongodb.database').

If I pass the default client using quarkus.mongodb.database, all my collections are created in the same database. However, the collections args for @MongoEntity works fine.

Expected behavior

When passing @MongoEntity(database = "userDB"), the collection should be created in the userDB database.

Actual behavior

If no default database is passed in application.properties, an error is thrown. Else the collection is created in the default database.

@romilpunetha can you link to a reproducer or upload one inside the issue ? This would help us on it a lot.

Here it is:
https://github.com/romilpunetha/quarkus-mongo-panache-demo/tree/main/mongodb-panache-quickstart

The following is the annotation on my UserEntity class:
@MongoEntity(database = "userDB", collection = "users")

However, the db is created using the base db config:
quarkus.mongodb.database=Users

@loicmathieu Did you get a chance to look into this?
We're about to move our workloads to production and it'd be difficult moving the collections into their respective DBs later.

Hi @romilpunetha there is indead a bug inside the reactive implementation that didn't take the database name from the entity.
I provided a PR to fix it.
