vim-patch:8.2.2782: Vim9: blob operations not fully tested

Browse Source 
Problem:    Vim9: blob operations not fully tested.
Solution:   Make more blob tests run in Vim9 script.  Fix filter().  Make
            insert() give an error for a null blob, like add().

vim-patch:8.2.3284: no error for insert() or remove() changing a locked blob

Problem:    No error for insert() or remove() changing a locked blob.
Solution:   Check a blob is not locked before changing it. (Sean Dewar,
            closes vim/vim#8696)
