Brad Fitzpatrick 7b5b9f5ce2 client/web: fix nil metricCapture crash in mockLocalAPI
The upload-client-metrics handler called metricCapture without
checking if it was nil or if the metrics slice was empty. Most
tests pass nil for metricCapture, so if a metrics upload races
in during the test, it panics.

Fixes #19252
