Extra space for given name causes double period for rendered citation

I wasn't seeing this in the latest tag, but this seems to have been introduced with ✨ Deprecated packages in dependencies Fixed which has been merged into dev but not tagged in any release that I could see.

This does fix the issue for me, but I'm not sure if the fix would affect anything else, so I'm setting this to needs review.

I attempted to reproduce this problem on the 3.0.x-dev branch today and was unable to do so. Steps taken:

1. Create a new Contributor at /admin/content/bibcite/contributor , entering a Middle Name and a Surname, but not a First Name.
2. Create a Reference and associate it with this Contributor.
3. Render this using the (default) APA style citation formatter provided by the module.
4. Observe that there is no duplicative "double period" as described in the issue report.

I also tried populating a whitespace character for the first name, and separately for the middle name.

If this is still a problem, please provide additional steps to reproduce. Also, if it is a problem, it might more appropriately be addressed in https://github.com/ADCI/full-name-parser, which is a dependency of this module.
