Fix don't quote prompt when quote_char is empty string

[rafamadriz]

I already have a keymap to quote the prompt, so my current workflow is: type query-> Quote prompt -> Start adding options

However I would like to create keymaps for some common options I use, currently this not possible because when quote_char is emtpy, it still adds backslashes before each character in prompt, and this breaks the search pattern

Usecase is for chaining mulitple rg options without, quoting the prompt mulitple times, which is not the expected behavior when quote_char is empty string.

E.g Consider this keymap

["<C-;>"] = require("telescope-live-grep-args.actions").quote_prompt {
        postfix = " --word-regexp ",
        quote_char = "",
    }

And I search for tab, then pressing <C-;>:

Before:

\"\t\a\b\"\ --word-regexp

After:

"tab" --word-regexp

Hello, I would definitively need that feature too! Any chance of merging this?
@rafamadriz do you have a workaround for now?
Thanks!
