Escaped symbol arguments aren't handled correctly

[connorshea]

Escaped symbols, or string-symbols, or as I like to call them, 'abominations', don't get sent through to the generated file properly.

Input:

def create_server(name, region = :'eu-central')
  # code
end

Generated rbi method:

def create_server(name, region = eu-central) end

It looks like this may actually be an issue with YARD itself.

Take the following example code:

module Example
  class Foo
    def bar(x = :'abomination')
      3
    end
  end
end

It appears that the YARD registry (assigned to r here) doesn't include the : and apostrophes around the identifier:

irb(main):012:0> r.all(:class).first.meths.first.parameters
=> [["x", "abomination"]]

The generated YARD HTML docs also show the same issue!

This has now been fixed in YARD (lsegal/yard#1256).
