False positive for Style/RedundantArgument

[t-mario-y]

Expected behavior

String#chompmethod for '\n' (single quoted) should not be affected by Style/RedundantArgument cop, because special treatment in this method is "\n" (double quoted).

Actual behavior

Single quoted '\n' is also detected offence after this commit: 8b3656d

Steps to reproduce the problem

Targetting example Ruby file like contains 'foo'.chomp('\n'):

bundle ex rubocop --only Style/RedundantArgument single_quote_chomp.rb

Result:

Inspecting 1 file
C

Offenses:

single_quote_chomp.rb:1:12: C: [Correctable] Style/RedundantArgument: Argument '\n' is redundant because it is implied by default.
'foo'.chomp('\n')
           ^^^^^^
