Fix issue when no socket is defined

[foxted]

A client of mine had some issues with this package recently:

when exporting the database only without any socket defined, the exported file had only one table.

Hi,

Good spot!

I have tried your changes and it works like a charm, but when I run the tests they fail, even though Travis passes.

Can you try running the tests on your end? ( $ vendor/bin/phpunit)

That's odd, the tests pass on my end as well!
