Fail silently

Currently if I use Travis for testing then using this library makes tests fail as it does not gracfully fail if it does not find the .netrc file.

Thanks for reporting @madisvain .

The current behavior matches the behavior in the netrc module in the stdlib as of Python 3.6.

It looks like the behavior was changed for 3.7 by python/cpython#4537 . Now, an error is not raised if $HOME isn't set. I'll go ahead and update tinynetrc to match the new behavior.

Keep in mind that an error will still be raised if the netrc file is not found, so you'll need to handle FileNotFoundError accordingly.

@sloria that was quick - I was going to look into this over the weekend ... already done.

Thank you!
