patch 9.0.1830: Vim9: crash when accessing a null object
Problem: Vim9: crash when accessing a null object
Solution: Check accessing a NULL object in def function
An object is NULL when the variable is declared, but the constructor
isn't called. Accessing/setting a member on the object crashed Vim.
Note: this happens inside def functions, at script level things work
differently. Accessing a NULL object member results in E1360
(correctly), while setting a value on it results in E1012 (type
mismatch) so there's still something to fix.
