GeanyWrapLabel: fix rendering issues
GtkLabel may re-create its PangoLayout between calls leading to the
final layout used for rendering not to be set up with the appropriate
values for our sizing. Then, re-set up the layout each time we have to
deal with it and straight before GtkLabel renders it.
