Security: publish manager accepts data even if there are no registrations / advertisements for the entity

[thingsping]

I was running some tests and ran into a situation where there were no active registrations or advertisements.However publish manager was accepting publish messages and storing them. :

Quite interestingl, if an entity tries to publish after the registration has expired, then the server does send back a 403 Forbidden code

Use drvstubs/pubtests/pub_without_reg_ad.json to test this.

I am no longer able to reproduce this. I think that in the fix for other related issues in 40e0300, this has got fixed too

I did run into a variant of this. Will report this separately.
