patch 9.0.1727: minor problems with the teapot

Browse Source 
Problem: minor problems with the teapot()
Solution: remove the null check, update documentation

Update the builtin-function-list entry. (It implicitly returns 0, but such
functions usually use "none")

Also, tv_get_string_strict() can not return NULL, so remove that check

closes: #12647
