Search Result Uniqueness

SeeRM rapid7#8754

Cast the results of the query to an array and perform the uniq
function passing a block which provides uniqueness based
on the return value, which in this instance is ‘fullname’
This was done because the uniq function in AREL cannot take
a specific field for uniqueness, and the sophistication of the query
make grouping nearly impossible.  Initial testing showed negligible
speed difference to the user.
