unreliable test: "getRecommendations ... CodeWhisperer service invocation"

[justinmk3]

This test (and potentially others like it) have been observed to randomly fail in CI:

1) recommendationHandler
       getRecommendations
         should call telemetry function that records a CodeWhisperer service invocation:

      AssertionError [ERR_ASSERTION]: Expected values to be strictly deep-equal:
