Lint/RedundantSplatExpansion altering code in unsafe manner

[iHiD]

Hello. Thanks for your work on Rubocop.

I have an issue where Lint/RedundantSplatExpansion is incorrectly changing code.

# Example 1
# This is (correctly) left unchanged:
method = :some_method
args = Array.new(args, 'a')
res = send(method, *args)

# Example 2
# This is the same code with the variable inlined
method = :some_method
res = send(method, *Array.new(args, 'a'))

# Rubocop incorrectly changes Example 2 to:
method = :some_method
res = Array.new(args, 'a')

I can reproduce by pasting that code block into a file and seeing it change as it's linted.
