WPCS: 3.0 merge_custom_array()

[GaryJones]

Bug Description

The Sniff::merge_custom_array() function was moved to a new Helper class in WPCS: WordPress/WordPress-Coding-Standards#2157.

As per #734 (comment), it could still be used from WPCS, so the references (currently only 1) need updating when getting compatibility with 3.0.

VIP-Coding-Standards/WordPressVIPMinimum/Sniffs/AbstractVariableRestrictionsSniff.php

Line 130 in 8953e4a
