Bug 1222549 - Don't give up logging any stats when failing to submit to influxdb. r=jlund

Metrics submission in mozharness fails gracefully if there's a problem, but it
fails too early now that we're logging perherder data. This moves the guard
against repeatedly failing to submit to influx so that we will log
PERFHERDER_DATA even when influxdb submission fails.
