Broken parameter binding for GROUP BY time($interval) clause

[skoret]

Parameter binding works fine for WHERE clause, but it fails with parameters for time($interval) function in GOURP BY clause.
Properly formatted query should be like this: ... GROUP BY time(1m)
But InfluxDB.Client formats parameter with single quotes, like this: ... GROUP BY time('1m') and InfluxDB returns error: time dimension must have duration argument
