Trailing comma rule with mandatory comma should only trigger on multiline arrays

[jkooker]

The new trailing comma rule is very nice, and I want to turn it on for my multiline arrays. But that's triggering errors in my single-line arrays. It seems to me that the rule should only apply to multiline arrays.

In other words, can we make the following valid?

let x = [
    1,
    2,
    3,
]

let y = [1]

For .swiftlint.yml configuration:

trailing_comma:
    mandatory_comma: true

This is duplicate of #910 and was fixed in #912.

Please reopen if you still have this issue with the current (master) version.
