fix: creating Tasks with import statements

[bednar]

Closes #490

Proposed Changes

Fixed creating Task with import statement:

task_flux = 'import "http"\n\n' \
            'from(bucket: "iot_center")\n' \
            '    |> range(start: -30d)\n' \
            '    |> filter(fn: (r) => r._measurement == "environment")\n' \
            '    |> aggregateWindow(every: 1h, fn: mean)'
task = self.tasks_api.create_task_cron("my-name", task_flux, "10 0 * * * *", self.organization.id)

I think the fix is fine for most use cases. See comments.

The task option is now appended at the end of script. @rhajek, @powersj can you review the changes again?
