title: influxdb query with flux fails
body: <p>I try the following query to get data from the influxdb with flux syntax. Normal queries with the old syntax are working and with the CLi I can also query.</p>
  <pre><code> curl -XPOST localhost:8086/api/v2/query -sS -H 'Accept:application/csv' -H 'Content-type:application/vnd.flux' -d 'from(bucket: &quot;TvssDataContainer&quot;)'
  </code></pre>
  <p>I get the error:
  &quot;type error 1:14-1:31: undefined identifier &quot;&quot;TvssDataContainer&quot;&quot;&quot;
  What is wrong?</p>
  <p>If I query buckets like:</p>
  <pre><code>curl -XPOST localhost:8086/api/v2/query?db=TvssDataContainer -sS -H 'Accept:application/csv' -H 'Content-type:application/vnd.flux' -d 'buckets()'
  </code></pre>
  <p>I get:</p>
  <pre><code>#datatype,string,long,string,string,string,string,long
  #group,false,false,false,false,true,false,false
  #default,_result,,,,,,
  ,result,table,name,id,organizationID,retentionPolicy,retentionPeriod
  ,,0,_internal/monitor,,,monitor,604800000000000
  ,,0,TvssDataContainer/autogen,,,autogen,0
  </code></pre>
