Describe the bug

When treesitter gets disabled, you end up with no syntax highlighting at all -> :set syntax? returns syntax=on rather then e.g. syntax=c for a C file.

Steps to reproduce

• run nvim --clean a.c
• check that :set syntax? returns syntax=c
• run :lua vim.treesitter.stop()
• check that :set syntax? returns syntax=on

Expected behavior

The value of syntax should be restored to the proper syntax for the filetype, e.g. syntax=c for a C file.
