Fatal Error if scriptSrc is empty

[Acconitum]

Hi Dirk

I noticed, that there is a fatal error if you leave the scrtiptSrc property (script_src in database) empty within the backend.
I suggest to initiate the srcipt_src column with a default value of an empty string instead of null so the property can still be empty without any fatal errors in the frontend.

Let me know if you like me to open a pr for you.

It seems like the error only appears if you create a new entry and leave scriptSrc blank.
If you add a value and delete it right afterwards, TYPO3 will save the new value as an empty string and the error disappear
