Remove never-changing variable

[eileenmcnaughton]

Overview

CRM_Utils_Address::formatMailingLabel is called from 3 places in the code & I found none in the rest of universe. Of those 3
all pass the same values for $mailing - ie TRUE. This PR removes the usage of that variable - such that it is assumed to be TRUE (as this stage the signature is unchanged)

Before

Always true variable passed in

After

Variable no longer relevant - the test instance no longer passes the unused params but the others still do as $tokens at the end is still populated
