When try to get body I have error NoMethodError: undefined method `closed?' for nil:NilClass

[DmytroKondratiuk]

In version "1.1.0" when try to get body I have error. For example:

 photo_url = any photo url
 SsrfFilter.get(photo_url).body

Error:

NoMethodError: undefined method `closed?' for nil:NilClass
raise IOError, 'attempt to read body out of block' if @socket.closed?

Can you share a sample url to reproduce the issue?

I get this same error with Carrierwave trying to set a remote url for an image.

I think my issue is caused by #56

For example
photo_url = 'https://ssl.gstatic.com/ui/v1/icons/mail/rfr/logo_gmail_lockup_dark_2x_r5.png'

In version 1.0.8 when we try get a photo SsrfFilter.get(photo_url) answer:

#<Net::HTTPOK 200 OK readbody=true>

In version 1.1.0 when we try get a photo SsrfFilter.get(photo_url) answer:

#<Net::HTTPOK 200 OK readbody=false>

Same issue for a private project that was solved by downgrading to 1.0.8

I confirm the fix by #60
