Describe the bug

After issuing:

:Clap history

If I hit Backspace I get something similar to what I would get if I would issue:

:Clap files

Remark: for some reason the order of the files is slightly different.

To Reproduce Steps to reproduce the behavior:

1. Create the minimal vimrc min.vim:

set nocompatible
set runtimepath^=/path/to/vim-clap
syntax on
filetype plugin indent on

2. Start Vim with command: vim -u min.vim

3. Type

   :Clap history

   You get the history of buffer visible in the dialog

Wait for the history dialog to come and hit Backspace

5. See error

You get the list of file you would have if you have issued:

:Clap files

Expected behavior

Get the same list of files you would get if you have only issued:

:Clap history

Remark: You have the same unexpected behavior if you type:

• some textCtrl-u or
• somewordCtrl-w

Should be fixed in the latest commit. It looks like switching to the files list, but not, when you press the backspace, it's an empty query, previously the filtering will start to work and then the order may be changed even for the empty query due to some contextual matching scheme. Now the behaviour of empty query is made to be consistent with what we see on intializing the provider.

I'll test and let you know :-)

[vds2212]

It works like a charm :-) Thanks you so much for your support!
