list: fix GUI_EVENT_THEME_CHANGED timing issue

Browse source 
Initialize a list's dirty_tick to last_dirty_tick instead of to the
current tick.

Issue probably only affects the sim:

To force a list to reinitialize using the GUI_EVENT_THEME_CHANGED
event, last_dirty_tick is set to the current tick.

list_is_dirty() checks whether the list viewport needs to be
re-initialized by comparing the list's dirty tick to last_dirty_tick,
and seeing if time has passed.

In some scenarios though, the list's vp may be initialized, become
immediately dirty, and list_is_dirty is called, all in the same tick.
