Release tools: In bug fixes per release script, add a check for when a user puts the word "broken" in the working field

Occasionally users will fill out a bug report with the fields like:
```
Broken: A
Working: Also Broken in B
```

This can lead to bug fixes per release script classifying the report
incorrectly.

This commit adds a small check that sees if "broken" is in the working
field, and if it is, then avoid adding the versions in that working
field to the list of working versions used for classifcation since we
can't trust it.
