Fix empty <ImageField> does not apply sx prop

[RoBYCoNTe]

If you have many menu items, navigating between them can produce temporary invalid records with empty sourceValue, in this case sometimes we received this error valid value for prop sx on

tag related to the usage of ImageField with specification of sx prop.

To avoid this we replaced standard div with Typography that can accept sx without problems.
