fix(picker): ensure that the selected result matches the screen display in ascending sort order

[0x7a7a]

Description

The current stable version (v0.9.5) and the nightly version have different results for the cursor position on the displayed content, I don't know exactly why.

After debugging, I found that this line of code causes the cursor to move down(row+1) when sorting_strategy=ascending,this result is consistent in v0.9.5 and nightly.

telescope.nvim/lua/telescope/pickers.lua

Line 436 in 67c598f

ok, msg = pcall(vim.api.nvim_buf_set_lines, results_bufnr, num_results, -1, false, {})

However, when the result is displayed, the highlighted row and the cursor position are not the same, so it cannot be displayed in nightly version(by default, the second result is displayed at the top, in the same position as the cursor.).

So I think putting the cursor to the first line (i.e. highest score) again in Picker:get_result_completor fixes the problem and doesn't affect older versions.

This is more obvious if the picker is another theme.
Ex:

pickers = {
  find_files = {
    hidden = true,
    theme = 'dropdown',
    previewer = false,
    follow = true,
  },
}
