[REF] Minor code simplification in dedupe.

[eileenmcnaughton]

Overview

Small readabilty code change

Before

Repeat references to $mainTree[$gid]['fields'][$fid]['customValue']
$foundField works as a clumsy isset

After

variable used for $mainTree[$gid]['fields'][$fid]['customValue']
$foundField replace by a ternary achieving isset

Technical Details

This just tweaks readability by

1. adding a variable for a value nested fairly deeply in an array
2. removing the foundField handling in favour of a ternary since
   it's kinda confusing as is
