normal service cant be injected to gorm abstract service

### Task List

- [x] Steps to reproduce provided
- [x] Stacktrace (if present) provided
- [x] Example that reproduces the problem uploaded to Github
- [x] Full description of the issue provided (see below)

### Steps to Reproduce

1. create normal service
```
package com.sinoregal.sonar

class CacheService implements InitializingBean{
RoleResourceRelationService roleResourceRelationService //this is gorm abstract service
void testRoleResourceRelationServiceIsNull() {
if(roleResourceRelationService == null) println "roleResourceRelationService in cacheService is null"
else println "roleResourceRelationService in cacheService normal"

}
...
}
```
2. create gorm service
```
package com.sinosonar.rbac.relation
@Service(RoleResourceRelation)
abstract class RoleResourceRelationService{

CacheService cacheService //this is normal grails service
void commandPermissionCheck(int roleId, String command) {
if(cacheService == null) println "cacheService in roleResourceRelationService is null"
else "cacheService in roleResourceRelationService normal"
}
}

```
3. call roleResourceRelationService.commandPermissionCheck and cacheService.testRoleResourceRelationServiceIsNull() in any controller

### Expected Behaviour
"roleResourceRelationService normal"
"cacheService normal"

### Actual Behaviour
"roleResourceRelationService in cacheService normal"
"cacheService in roleResourceRelationService is null"
also can set breakpoint to watch,will find the cacheService in roleResourceRelationService is null

### Environment Information
- **Groovy Version**: 2.4.15
- **Grails Version:** 3.3.5
- **JDK Version:** 1.8.0_181
- **Gradle Version:** 3.5

### Example Application

https://github.com/linchanghui/gorm-bug

### remark
i also try add @Autowired to cacheService in RoleResourceRelationService, Although it make cacheService in roleResourceRelationService be injected
such：
```
@Service(RoleResourceRelation)
abstract class RoleResourceRelationService{

@Autowired
CacheService cacheService
```
however it will result roleResourceRelationService in CacheService is null

Start by running the linked gorm-bug example application with the stated Grails, Groovy, JDK, and Gradle versions. Inspect CacheService and RoleResourceRelationService, then reproduce the controller calls and compare injection behavior with and without @Autowired. Done means both services receive their dependencies without breaking the reverse injection.
