hooks.py(fix[unset_hook]): Remove invalid ignore_errors parameter

why: tmux set-hook (used with -u for unset) does not accept -q flag.
     Verified against ~/study/c/tmux/cmd-set-option.c:65 which shows
     set-hook accepts "agpRt:uw" only.
what:
- Remove ignore_errors parameter from unset_hook() signature
- Remove ignore_errors flag handling code
