Squiz.WhiteSpace.MemberVarSpacing false positives when attributes used without docblock

[javer]

Fixes false positives when class properties are declared with attributes and without DocComment.
Without this fix it's impossible to use only attributes for properties without DocComments, because this sniff forces you to insert blank line between the property and the attribute:

Expected 1 blank line(s) before member var; 0 found (Squiz.WhiteSpace.MemberVarSpacing.Incorrect)

@gsherwood Could you please take a look on this simple fix, which allows everybody to use property attributes without doc-comment?

This is a more selective fix compared to PR #3334, which is open for the same and has an associated discussion open in #3419.

Rebased on the latest master to make the build green.

Thanks for finding, reporting, and fixing this.
