fix bug where cancelling search in menu caused issue

This keybinding has been more pain than it's worth. Having a tab keybinding
to cycle tabs implies that you can shift+tab and when you shift+tab the
application exits because termbox, our dependency, doesn't know how to
interpret the escape sequence (so it takes it for an actual ESC key which
will exit lazygit at the top level).

If people get mad at me they can set nextBlock-alt to <tab> and they'll have
the functionality back :)

 A simple terminal UI for git commands, written in Go with the [gocui](https://github.com/jroimartin/gocui "gocui") library.
 
 Rant time: You've heard it before, git is _powerful_, but what good is that power when everything is so damn hard to do? Interactive rebasing requires you to edit a goddamn TODO file in your editor? *Are you kidding me?* To stage part of a file you need to use a command line program to step through each hunk and if a hunk can't be split down any further but contains code you don't want to stage, you have to edit an arcane patch file _by hand_? *Are you KIDDING me?!* Sometimes you get asked to stash your changes when switching branches only to realise that after you switch and unstash that there weren't even any conflicts and it would have been fine to just checkout the branch directly? *YOU HAVE GOT TO BE KIDDING ME!*
