fix(lua): SIGSEGV in luv callback with error(nil) #32595
Problem:
luv callback `vim.uv.new_timer():start(0, 0, function() error() end)`
causes SIGSEGV, since `xstrdup` gets NULL from `lua_tostring`.
Similar to: https://github.com/neovim/neovim/commit/a5b1b83a2693ffa7a5a0a22b3693d36ea60051be
Solution:
Check NULL before `xstrdup`.
