Describe the bug From version 5.1.5 (PR) ImportingMikroOrm with forRootAsync and injecting any dependency in useFactory results in error.

Stack trace

TypeError: Cannot read properties of undefined (reading 'get')

To Reproduce Steps to reproduce the behavior: Use MikroOrmModule.forRootAsync() and inject any dependency to useFactory.

@Module({
  imports: [
    ConfigModule.forRoot({ isGlobal: true }),
    MikroOrmModule.forRootAsync({
      inject: [ConfigService],
      useFactory: async (configService) => {
        return {
          entities: [
            './dist/domain/**/model/*.js',
          ],
          dbName: configService.get('database.name'),
          type: 'postgresql',
          user: configService.get('database.user'),
          password: configService.get('database.password'),
          port: configService.get('database.port'),
          host: configService.get('database.host'),
          migrations: {
            path: __dirname + './dist/persistence/migrations',
            pattern: /^[\w-]+\d+\.js$/,
          },
        };
      },
    })
  ]
})

Expected behavior You should be able to use async provider without any errors thrown.
