Don't require history matches in completing-read

Browse source 
Currently, eshell-atuin's `eshell-atuin-history` doesn't allow
inserting commands that aren't yet in the history. This patch proposes
unmatched commands are inserted even if they don't match.

Consider the following scenario; you're running eshell-atuin with
`eshell-atuin-history` bound to `C-r`. In Eshell, you type part of a
command, let's say `ls`. Because the command you're looking for should
be in Atuin's database, you press `C-r` and find `ls -l`. That's
helpful, but not the full command you're looking for. You press
`<tab>` to insert the match and add `ah` to get `ls -lah`, the command
you meant to execute. However, after pressing `<ret>`, you find that
eshell-atuin won't let you insert a command that's not in the history
yet.

This patch flips the `REQUIRE-MATCH` boolean in the `completing-read`
call in `eshell-atuin-history` to `nil`, allowing for commands that
aren't in the history yet.

The resulting `compl` variable, which holds the command is then used
to find the command in the history. This is done to make sure any
changes to `eshell-atuin-history-format` don't affect the inserted
command. However, because there is no match in the history in this
scenario, the `command` variable remains empty.

In the end, what's inserted is either the cleaned `command` variable
which mached in the history, or the `compl` variable that didn't
match, and is inserted as-is.
