Final dot in name is stripped by import

When importing contacts, if the name has a dot as final character (for example, an organization with acronym at the end of organization name or an individual with initials in first or last name), the final dot will be stripped from the name field.

This results in data loss if the dot is "supposed" to be there. Also if the contact is a duplicate of an existing contact, it will not be detected as a duplicate because of the missing final character.

I verified this bug on the demo site with a CSV file like this:
"test.","1.","mark@example.org"
