Predeclared String Variables are being populated as "0" when empty instead of ""

[Silver-Streak]

Is there an existing issue for this?

Describe the bug

Found via Jack on the forums, https://forum.gdevelop.io/t/empty-text-variable/57079/3:

If you predeclare a string variable, and set it to an empty string, the actual string is set to "0" as shown in the debugger or if called via expressions.

I went back and tested before the variable update, and this is new behavior. Previously it would default to "" when the string was empty.

If I had a guess, my bet would be that the "always force number variables to have 0 if empty" is applying to the string variables as well.

Steps to reproduce

1. Create a global, scene, object, or instance variable.
2. Change the type to string.
3. Delete anything after it.
4. Run the preview with debugger.
5. The variable's string will be "0"
