Fixes $options = null check when use Zend\Valdator\Barcode

[samsonasik]

the constructor has optional $options = null but no check for it, this PR fixes it.

Next if initialize the adapter value as null and getAdatper has a test for it and then do a lazy initialization.

Can you paste the results of the added test without "the fix"?

[Maks3w]

Don't detail constructor types in the function name, this is already provided by the provider.

updated

[samsonasik]

without the fix, it will got error:

    Adapter NULL does not implement Zend\Validator\Barcode\AdapterInterface

[Maks3w]

Then the source of the issue is:

1. getAdapter try to lazy initializate the adapter if this one does not exists
2. parent constructor calls setAdapter with null value and setAdapter check if the argument is a valid instance.

For me the easiest solution is allow null on setAdapter

[samsonasik]

@Maks3w I've updated setAdapter() to allow null

[Maks3w]

Your choice of set an empty array is better

[samsonasik]

if use set empty array, it will got:

Zend\Validator\Exception\InvalidArgumentException: Adapter array does not implement Zend\Validator\Barcode\AdapterInterface

[Maks3w]

With this? #52 (comment)
