trailing_comma incorrectly flags [SomeType]()

[ZevEisenberg]

This code:

var imageViews = [UIImageView]()

is causing a warning when I have this in my SwiftLint configuration:

trailing_comma:
  mandatory_comma: true

This is with SwiftLint 0.13.1.

Let's try to minimize the false positives and make sure the following doesn't trigger with mandatory_comma:

[Void]()
[(Void, Void)]()

Perhaps we can kill two birds with one stone by not reporting violations for single-line collections as reported in #910.

Fixed by @marcelofabri in #912.
