Move g_return_if_fail to top of function and exit early.

This way the meat of the function isn't needlessly indented.
I think it's easier to read code structured this way.
/** @page imgstore-signals Image Store Signals
@signals
@signal image-deleting
@endsignals
@see imgstore.h
<hr>
@signaldef image-deleting
@signalproto
char *(*image_deleting)(const PurpleStoredImage *img);
@endsignalproto
@signaldesc
Emitted when a #PurpleStoredImage is about to be destroyed. This allows
for what amounts to weak references. Code can hold onto a pointer to
the PurpleStoredImage without actually "holding" a reference. They can
then use a signal handler to let them know when their img is about to
be destroyed.
@param img The image about to be destroyed.
@note It's not possible to purple_imgstore_ref() img to save it.
@endsignaldef
