Handle empty TranslationInfo tag properly when parsing Settings.xml

[pmachapman]

Fixes #401.

I tested by modifying the Settings.xml file manually. If you think this should have its own test, we will need another test project in the file system, as none of the file system calls go through an abstraction layer.

I think it would be helpful to have a test fixture for ParatextProjectSettingsParserBase to test this kind of logic. We can create a memory-based implementation for testing purposes. MemoryParatextProjectFileHandler already exists.
