Fix crash when startup file has an image in it

This fixes an issue introduced in d192d723123add1dde3e9f7e9458aefcafb7e7d2.
When starting up, the UI hasn't been fully initialised yet, and calling
wm_event_do_depsgraph() can trigger icon updates when the startup file
contains an image, causing a segfault due to a not-yet-initialised ghash
for the icons.
