Some cached public publickey atkeys cannot be deleted (atkeys that are like:cached:public:publickey@)

[JeremyTubongbanua]

Initial question (March 21)
How come I am able to delete some cached public keys in my atServer (cached:public:publickey@soccer99), but not able to delete some like this one (cached:public:publickey@jeremy_0). The atSign I'm authenticated as is @soccer0

@Jeremy Tubongbanua I think it's a bug. cached public keys are not protected keys, so deletion must be allowed.

Expected behaviour is to be able to delete cached public keys, but some are able to and some are not able to.

Sprint points allocated to this ticket involve fixing this bug and achieving expected behaviour.
