Fix a flake in amqp_client_SUITE (backport #11234)

[mergify]

event_recorder listens for events globally rather than per-connection so it's possible for connection_closed and other events from prior test cases to be captured and mixed with the events the test is interested in, causing a flake. For example: https://app.buildbuddy.io/invocation/f31d0f74-02f9-407c-887c-838e0952f60a?target=%2F%2Fdeps%2Frabbit%3Aamqp_client_SUITE&targetStatus=6#1

Instead we can assert that the events we gather from event_recorder contain the ones emitted by the connection.
