Regression of URI.parse in 0.12.0

[shioyama]

We noticed this issue bumping URI from 0.11.0 to 0.12.0:

# ruby/uri 0.12.0
URI.parse("https://").host
#=> ""

# ruby/uri 0.11.0
URI.parse("https://").host
=> nil

The issue seems to be 81263c9. Is this an intentional change? If so it should be mentioned in the release notes for 0.12.0 no?
