Victoriametrics: VM ignore some metrics, received from influxdb clients

[0xBF]

Some influxdb clients (at least ruby client) send metrics without trailing newline. If there is only one metric in request, it ignored. In some cases can be ignored the last metric in batch requests.

example request:

curl -sd "mymetric test=10i 1559933640" 'http://172.17.0.3:8428/write?db=qq&precision=s'

check metrics:

curl -s 'http://172.17.0.3:8428/metrics' |grep influx
vm_http_request_errors_total{path="/write", protocol="influx"} 0
vm_http_requests_total{path="/query", protocol="influx"} 0
vm_http_requests_total{path="/write", protocol="influx"} 1
vm_read_calls_total{name="influx"} 1
vm_read_errors_total{name="influx"} 0
vm_rows_inserted_total{type="influx"} 0
vm_unmarshal_errors_total{name="influx"} 0

It can be fixed by commenting this line:
