fix: imc dispatcher doesn't have duplicate reporting of metrics

[Cali0707]

Fixes #7869

We were always recording the metrics once, and then if there was http or https we were recording the metric a second time. This fixes that to only do the recording of metrics once with the scheme set.

Proposed Changes

• Remove the extra call to record the metrics

Release Note

:bug: The IMC dispatcher metrics now correctly record the metrics once per event when there is only one request scheme, instead of twice
