Add DCHECK that disable is not set, similar to the two functions below?

 
 void EnableNewProfileManagementForTesting(base::CommandLine* command_line) {
   command_line->AppendSwitch(switches::kEnableNewProfileManagement);
   DCHECK(!command_line->HasSwitch(switches::kDisableNewProfileManagement));
 }
 
 void EnableAccountConsistencyForTesting(base::CommandLine* command_line) {
   command_line->AppendSwitch(switches::kEnableAccountConsistency);
   DCHECK(!command_line->HasSwitch(switches::kDisableAccountConsistency));
 }
 
 }  // namespace switches
