[Bug] Failed speedtests shouldn't write to the `server_id` column

[alexjustesen]

          It is writing that property though

speedtest-tracker/app/Jobs/Speedtests/ExecuteOoklaSpeedtest.php

Lines 65 to 69 in 9a0d7da

	$this->result->update([
	'server_id' => $this->serverId,
	'data' => json_decode($message, true),
	'status' => ResultStatus::Failed,
	]);

so maybe this needs to be updated? Either way currently this app doesn't function as a fresh install.
