strange errors even though migration worked

[Schnitzel]

with a recent customer we saw some strange errors in the operator (v0.1.9)

2021-01-21T01:21:03.152Z	INFO	controllers.IngressMigrate	Unable to delete certificate  in namespace ; error was: resource name may not be empty	{"ingress": "/"}
2021-01-21T01:21:03.152Z	INFO	controllers.IngressMigrate	Unable to patch secret  in namespace ; error was: resource name may not be empty	{"ingress": "/"}
2021-01-21T01:21:03.152Z	INFO	controllers.IngressMigrate	Added delete annotation to secret  in namespace 	{"ingress": "/"}

the active/standby switch worked though without a problem.
