Properly wrap `kak_assert` into a do-while scope
Expanding the `kak_assert` macro to either an `if` statement or nothing
leads to issues when the macro is used in a conditional statement that
doesn't use braces.
Example: ncurses_ui.cc:476, in non debug mode, the macro will expand to
an empty line, resulting in the `ungetch` call not being executed if the
`ioctl` call succeeds (line 448).
