fa2ecadd0d3283a89d27772dc0275e76277ae17e test: Fix intermittent rpc_net issue (MarcoFalke) Pull request description: The test fails because getpeerinfo and getnettotals are not synchronised, so a `wait_until` is needed for each RPC (separately). Fixes https://cirrus-ci.com/task/4663366629195776?command=ci#L5034 ACKs for top commit: jnewbery: utACK fa2ecadd0d3283a89d27772dc0275e76277ae17e Tree-SHA512: 5ea7128801aab8dbe3d9e6737545ff4ee770e4a9c5a2096ba2339a688424f1879ccba6bf8bcb219983acf86eb28af06fc629586613e7fe28aeffadd2c98633e8
