Fix for lack of null safe property access while looking for file input.
Fix #559
Notice:
IMHO usage of hasFileField meta property should be dropped in favour of discovering File object by dataProvider itself, what is happening partly already ( containFile / findFile functions), and should be possible to override updateHttpMethod, multipart PUT request could be successfully processed on backend site by using for example notihnio/php-request-parser .
