Remove layout_initialise() calls from content_resize_request()

Browse Source 
The calls were there to work around automatic rewrapping of text caused by
a hack in `scroll_label::set_label()`. @Vultraz removed that hack in commit
ae76bb0efbc53f102cc772ace3941c5867e2c91c. After that, there wasn't any
reason to call `layout_initialise()` any more.

Well, other than that removal of scrollbars set as `AUTO_VISIBLE_FIRST_RUN`
relied on full layout initialization. I implemented a secondary, faster
mechanism for that.

This commit removes unnecessary code, and speeds up switching between
add-ons in the add-on manager further still.
