ZyX 1162962d8b functests: Refactor tests:
- Remove unused variables.
- Do not use helpers.nvim_feed in most cases.
- Do not use helpers.nvim and helpers.nvim_eval at all.
- Add helpers.funcs and helpers.\*meths special tables. Indexing such table 
  creates functions which call helpers.call or helpers.nvim (and similar) with 
  first argument equal to table index.
