Fix pango title escaping

Browse source 
This commit fixes two bugs.

First, commit [1] has inverted the condition when we escape pango markup. We
need to escape client-provided strings when markup is enabled.

Second, parse_title_format has a shortcut when title_format is set to `%title`,
and escape_pango_markup wasn't used anymore there.

Fixes https://github.com/swaywm/sway/issues/3181
