MimeType validation error

[juniwalk]

Hi, me again with validation issues. :)

I had edge case where MimeType returned was null and Validator has failed because of strtolower call.

There should probably be return $mimeType ?? ''; so it is always string.

That's a bug in validator from nette/forms (see your stack trace). This would fail even with normal FileUploadControl. This needs to be addressed in Nette itself.

@xificurk Oh I just thought that it was issue inside FileUploadControl. Alright thanks.
