Do not report SA1516 for two consecutive single line properties

[FantasyTeddy]

This relaxes SA1516 as suggested in #2441:

• If two properties are both single line, they do not require a blank line in between.

Since this change makes StyleCop behave less strict, I'm not sure if this behavior should be configurable. Let me know if it should.
