Current behaviour

Currently CI reports that all RPCs are covered: https://cirrus-ci.com/task/6244871116161024?logs=ci#L4674

Expected behaviour

However, some RPCs are clearly not covered because they are never called. For example:

$ git grep abortrescan  ./test/  | grep -v '. Please call `abortrescan` before ' | wc -l 
0
