duplicate items when registering the branch

[HanKaiqiang]

• [ ] I have searched the issues of this repository and believe that this is not a duplicate.

Ⅰ. Issue Description

lockKeys have the duplicate items, like this: _lockKeys = ci_73_978_njrs:307;ci_73_978_njrs:307,308;ci_73_978_njrs:307,308,309,310,311;ci_73_978_njrs:307,308,309,310;ci_73_978_njrs:307,308,309,310,311,312;ci_73_978_njrs:307,308,309,310,311,312,313,314;ci_73_978_njrs:307,308,309,310,311,312,313;ci_73_799_pjct:14;trigger_tasks_73:167470;ci_73_978_njrs:307,308,309;trigger_task_change_logs73:150222

Ⅱ. Describe what happened

when the @Transactional is under the @GlocalTransactional, and the method is called recursively in many hierarchies

Ⅲ. Describe what you expected to happen

lockKeys should be: _lockKeys = ci_73_978_njrs:309;ci_73_978_njrs:307;ci_73_978_njrs:308;ci_73_978_njrs:314;ci_73_978_njrs:312;trigger_tasks_73:167471;ci_73_978_njrs:313;ci_73_978_njrs:310;ci_73_799_pjct:14;ci_73_978_njrs:311;trigger_task_change_logs73:150223

Ⅳ. How to reproduce it (as minimally and precisely as possible)
