Reduce flakiness on tracing tests

[adriangonz]

Context

Jaeger processes the tracing spans asynchronously, so there is a slight delay between an action happening and Jaeger reporting the full trace. Because of this, the integration tests introduced in #1464 may fail some times (when we fetch the requests while not all of them have been processed yet).

Changelog

• Retry Jaeger tracing request if the trace seems incomplete.
