Individual Organization name when Contact has no first name starts with "null "

What steps will reproduce the problem?
1. Create a new contact/individual organization
2. Edit the first name and/or last name in such a way that the first name 
becomes or remains blank
3. The name of the Organization object will now be "null Lastname" instead of 
just "Lastname" - note that this does not occur on creation of the two objects, 
only on an update of the Contact

What is the expected output? What do you see instead?
If the Contact's first name is blank, the Organization object should remain 
just "Lastname" like it is on creation

What version of the packages are you using?
Both 2.0.2 and 2.1.2

Please provide any additional information below.
