InfluxDB 1.x: No error and data are silently ignored in case of invalid time precision

[vlastahajek]

Steps to reproduce:
Write data with invalid precision constant in the write URL:

curl -v -XPOST "http://localhost:8086/write?db=test&precision=x" --data-raw "wifi_status,SSID=AB,device=ESP32 rssi=-31 1586189309000003"

*   Trying ::1...
* TCP_NODELAY set
* Connected to localhost (::1) port 8086 (#0)
> POST /write?db=test&precision=x HTTP/1.1
> Host: localhost:8086
> User-Agent: curl/7.55.1
> Accept: */*
> Content-Length: 60
> Content-Type: application/x-www-form-urlencoded
>
* upload completely sent off: 60 out of 60 bytes

Expected behavior:
Either:
1 - write data
2 - return 500 as it InfluxDB 2 does

Actual behavior:
The server returns status as if data is written successfully
< HTTP/1.1 204 No Content

Environment info:

• System info: Windows 10 Professional
• InfluxDB version: 1.8.0rc1
