bug#66149: Mistyping a search breaks keyboard macro

[Konstantin Kharlamov]

If a user recorded a keyboard macro, upon replaying they expect the actions 
will be executed exactly as performed during recording.

Unfortunately that doesn't hold for searches, which is unfortunate, because 
search is very useful during keyboard-macros. If a user mistypes a search, they 
usually just remove the offending letters and it just works. However replaying 
such record fails with `Keyboard macro terminated by a command ringing the bell`

# Steps to reproduce

1. `emacs -Q`
2. Press `F3` to start recording a macro
3. Press `C-s` to start search and type `bufg`. The letter `g` will get 
highlighted in red because there's no such word
4. Press Backspace to remove `g` letter
5. Press `f` so the word is `buff`
6. Finish the macro by pressing `F4`
7. Execute the macro by pressing `F4`

## Expected

Search succeeds

## Actual

Search fails with `After 0 kbd macro iterations: isearch-search: Keyboard macro 
terminated by a command ringing the bell`
