call_arg_parentheses = always not working for string arguments when quote_style = double

[alex-courtis]

Correct

call_arg_parentheses = always functions correctly, adding parentheses to all calls:

call_arg_parentheses = always

foo 'a'
foo "b"
foo {}

is formatted as

foo('a')
foo("b")
foo({})

Incorrect

Adding a quote_style results in incorrect formatting for strings only:

quote_style = double
call_arg_parentheses = always

foo 'a'
foo "b"
foo {}

is formatted as

foo"a"
foo"b"
foo({})
