MS crashing when trying to execute here-doc

[tesla33io]

Trying to run here-doc in minshell causes it to crash. The issue is in parsing, namely - when trying to print error with data from token_stream which is null at that point (after multiple recursive calls).

Logs from core file and gdb:

Tried to change check for null in this function:

src/parser/parser.c:71
-if (!token_stream && !production && !shell_data->lexer->unmatched)
+if (!token_stream || !production || !shell_data->lexer->unmatched)

It didn't fixed the problem, but prevented MS from crashing.
