no preview of time series when header attributes are quoted

[jdevoo]

Describe the bug Cannot view the time series data in labeling task preview when the dataset header attributes are quoted.

To Reproduce Steps to reproduce the behavior: Create a local data source and add location for dataset (below first few rows)

"timestamps","value","anomaly","changepoint","trend","noise","seasonality1","seasonality2","seasonality3"

Create project with following task (adjust path and filename accordingly)

[{
  "data": {
    "csv": "http://localhost:8080/data/local-files?d=online-SESD/A3Benchmark-TS1.csv"
  }
}]

Labeling UI was configured as follows

<View>
  <TimeSeriesLabels name="A3Benchmark" toName="TS1">
    <Label value="mycp" background="red"/>
  </TimeSeriesLabels>
  <TimeSeries name="TS1"
              timeColumn="timestamps"
              timeFormat="%s"
              valueType="url"
              value="$csv">
    <Channel column="value"/>
  </TimeSeries>
</View>

Go to project and select labeling task. See that preview panel remains gray. When I remove the double quotes from the time series dataset, I see the time series data in the task.

Expected behavior I would expect the data can be read with and without quoted header attributes.

Environment (please complete the following information): I used the docker image of Label Studio 1.7
