the error of getting acctKey

[czh0526]

in the file of waddrmgr/scoped_manager.go at line 1246:

    watchOnly := s.rootManager.WatchOnly() || acctInfo.acctKeyPriv != nil
if !s.rootManager.IsLocked() && !watchOnly {
	acctKey = acctInfo.acctKeyPriv
}

would it be written as this:

   watchOnly := s.rootManager.WatchOnly() || len(acctInfo.acctKeyPriv) == 0
if !s.rootManager.IsLocked() && !watchOnly {
	acctKey = acctInfo.acctKeyPriv
}

In this context, both variants are equivalent. Do you have a test case demonstrating otherwise?

acctInfo.acctKeyPriv != nil is completed different with len(acctInfo.acctKeyPriv) == 0
