Remove name from greeting/contact when person is marked deceased.
And the rubocop error is that you can put the condition at the end of the line if its is a 'single-lined body'.
`c.greeting = c.greeting.sub(' and ', '').strip unless c.greeting.index(' and ').nil?`

Also, instead of checking and and assigning, this whole condition could be writen as:
`c.greeting.sub!(' and ', '')`
Running sub on a string that doesn't have the test doesn't do anything, and the `!` is the 'destructive' version of the method.
