Runtime fix for:

runtime error: Cannot read null.name
proc name: New (/obj/effect/golemrune/New)

The reaction that creates the rune was creating the rune in nullspace, it tried to use the loc in it's constructor, then it set the loc afterwards. Now it runs the constructor and such, THEN runs 'announce_to_ghosts()' after it is assigned a loc.

I've also changed src.loc.name to get_area(src) so instead of "A golem rune was created in area Floor " it says "A golem rune was created in Chemistry."
