fix(treesitter.foldexpr): only refresh valid buffers

Browse Source 
Problem: autocmd to refresh folds always uses the current buffer if the
option type is local. However, the current buffer may not have a parser,
and thus the assert that checks for a parser could fail.

Solution: check if the foldinfo contains the buffer, and only refresh if
so.
