Show adequate error if fileStorageUploadField is bound to wrong attribute type

[alexbudarov]

// wrong type
    @PropertyDatatype("uri")
    @JmixProperty
    @Column(name = "QUESTION_PICTURE")
    private URI questionPicture;

                <fileStorageUpload id="questionPictureField" property="questionPicture"
                                   permittedExtensions=".png,.jpg,.svg" fileStoragePutMode="IMMEDIATE"/>

In runtime opening such screen fails with unexpected error:

Expected:
Some nice DevelopmentException explaning that fileStorageUploadField doesn't support URI attribute type.
