tests: bless remaining tests

These tests just need blessing, they don't have any interesting behaviour
changes.

Some of these tests have new errors because `LegacyReceiver` cannot be
proven to be implemented now that it is also testing for `MetaSized` -
but this is just a consequence of the other errors in the test.
