Bug #10669: Incorrect url parsing in 2.2.0 
https://bugs.ruby-lang.org/issues/10669

----------------------------------------
Ruby 2.2 is incorrectly treating invalid URLs as correct due to parser change.

Ruby 2.2.0

```
irb(main):001:0> require 'uri'
=> true
irb(main):002:0> URI.parse("http://hello.com()")
=> #<URI::HTTP http://hello.com()>
irb(main):003:0>
```

Ruby 2.1 

```
require 'uri'
=> true
irb(main):002:0> URI.parse("http://hello.com()")
URI::InvalidURIError: the scheme http does not accept registry part: hello.com() (or bad hostname?)
	from /home/sam/.rbenv/versions/2.1.2.discourse/lib/ruby/2.1.0/uri/generic.rb:214:in `initialize'
	from /home/sam/.rbenv/versions/2.1.2.discourse/lib/ruby/2.1.0/uri/http.rb:84:in `initialize'
	from /home/sam/.rbenv/versions/2.1.2.discourse/lib/ruby/2.1.0/uri/common.rb:214:in `new'
	from /home/sam/.rbenv/versions/2.1.2.discourse/lib/ruby/2.1.0/uri/common.rb:214:in `parse'
	from /home/sam/.rbenv/versions/2.1.2.discourse/lib/ruby/2.1.0/uri/common.rb:747:in `parse'
	from (irb):2
	from /home/sam/.rbenv/versions/2.1.2.discourse/bin/irb:11:in `<main>'
```

This is a breaking change.
