handle bad ernest project names

[willkg]

Currently, the name of a project in Ernest must exactly match the product name in Bugzilla. If you enter in a project name that's different, then Ernest flips out when trying to retrieve stuff from bugzilla and you get errors like:

ValueError: max() arg is an empty sequence

This issue covers fixing any of the minor problems in this issue so that this doesn't happen.

This is true of bad sprint names, too.
