Anna Shaleva 2872c1c668 core: move contract notifications check under HFBasilisk
Follow the https://github.com/neo-project/neo/pull/2884.
A part of the https://github.com/neo-project/neo/pull/2810.
Fix failing tests along the way (a lot of them have invalid notifications
format which differs from the one declared in manifest).
