fix(createBranch): preserve user-provided title and path when autoSync is enabled

[mlewandowski904]

Ticket

#659

Summary

• Fixed a bug in commonService createBranch where user-provided path and title
  were silently overwritten by auto-generated values whenever autoSync was set to true,
  even when the user had explicitly set them
• Aligns backend behavior with the existing frontend logic, which already preserved user-provided path
