Title: Check for empty <tr> in pbgc scraper before attempting to set variable b...

Some of the markup on the PBGC site isn't valid (using tr with no slash as a closing tag), which is causing trouble:

```

OIG Response to Rep. Turner Request - Delphi Salaried Pension Plan Delays
LTR 2014-13
09/02/2014

```

So this commit just does a check to make sure that the tr has a nested td before doing its thing.
