Fix multiple parachain headers submission for single message delivery (#1916)

* switch off parachains relay when we don't need to relay parachains (temp solution)

* parachains relay now only works with single parachain

* fix usages of parachains relay

* revert hacky fix

* fixes

* fixed Westmint parachain ID

* fixed metrics

* fixed compilation

* fmt

* clippy

* call -> typed_state_call
