schwab_csv importer raises AssertionError because CSV has no title line

[kerrickstaley]

Summary

The CSV that I downloaded from Schwab at https://client.schwab.com/app/accounts/history doesn't have a Transactions for account... line, so I get an AssertionError when trying to import it.

To reproduce

1. Download a CSV by going to https://client.schwab.com/app/accounts/history and clicking the download icon in the top right. The first line of the CSV should be:

   "Date","Action","Symbol","Description","Quantity","Price","Fees & Comm","Amount"
   

2. Put the CSV in your "transactions" directory that you pass to transactions=glob(...) in your config
3. Run beancount-import

Expected behavior

No error

Actual behavior

You get this exception:

Notes

Is there is a different place I should be downloading CSVs from? If so, it should be documented in the docstring at https://github.com/jbms/beancount-import/blob/master/beancount_import/source/schwab_csv.py .
