gnome-text-editor crashed with SIGSEGV in editor_text_buffer_spell_adapter_invalidate_all() from editor_document_load_notify_completed_cb() from g_closure_invoke() from g_hash_table_lookup_node() from g_hash_table_lookup()

[errors.ubuntu.com bug bridge]

[ Impact ]

When launching gnome-text-editor by opening a file the window appears briefly before crashing if there was an unsaved draft.

This was fixed upstream by adding a NULL check.

[ Test Case ]

 * In the terminal run `gnome-text-editor`

 * Create a new tab

 * Type anything in the document, without saving.

 * In the terminal press Ctrl+C to terminate the process.

 * In the terminal run `gnome-text-editor foo.txt`

 * Verify that Text Editor launches without crashing.

[ What could go wrong ]

gnome-text-editor is the default text editor in Ubuntu Desktop; if it is not working the user could look for alternative text editors in the application store.

The patch is very unintrusive, it just adds two NULL checks.
We do not expect any possible regression.
