fix(codewhisperer): clear telemetry logger to avoid flaky test case #2945

Problem:
In some situation telemetry test case in CodeWhisperer may fail. The
assertTelemetry compares a deep equal of the first telemetry record it gets from
the queries.

Solution:
Clean the telemetry records before each telemetry test case.
