Can't locate object method "read" via package "IO::File"

With 0.05 and perl 5.12.x the test suite fails:

#   Failed test 'No tests run for subtest "return error when content length not equals actual read data"'
#   at t/transport/jsonp-send.t line 40.

I vaguely remember that this can be fixed with a "use IO::File", but I can be wrong.

With older perls (5.10.x, 5.8.x) the error message is different:

Can't locate object method "read" via package "IO::Handle" at /home/cpansand/.cpan/build/2018082618/SockJS-0.05-0/blib/lib/SockJS/Transport/JSONPSend.pm line 51.

That's fixed in the previous issues.
