Bugfix: warm up UI_StoreTakeover's Takeovers in more cases - Reimplemented warmup of StoreFeatured/General/Limited to first spawn empty tiles and fill them up once tab is opened Turns out, we can open tabs of store without opening store itself, resulting in an access to uninitialize takeovers. Couple empty item icons remain, will fix next. Tests: navigated to the store and clicked through bunch of tabs and scrolled around.
