Writer produced empty file on some conditions

[webhive]

Hello!

If initialize writer this way (as specified here https://github.com/mbleigh/seed-fu/blob/master/lib/seed-fu/writer.rb#L7)

SeedFu::Writer.write('path/to/file.rb', :class_name => 'Person') do |writer|

result file is empty and has only single footer line

# End auto-generated file.

But if use io as first argument

SeedFu::Writer.write(File.open('path/to/file.rb', 'w'), :class_name => 'Person') do |writer|

it work fine as expected
