fix(api): issue state change is not idempotent

Browse source 
The PATCH if issue & pull request switched to use the service
functions instead. However, the service function changing the state is
not idempotent. Instead of doing nothing which changing from open to
open or close to close, it will fail with an error like:

 Issue [2472] 0 was already closed

Regression of: 6a4bc0289d
