Crash on long-throw inserter deconstruction

The mod Renai Transportation (0.8.0) caused a non-recoverable error.
Please report this error to the mod author.

Error while running event RenaiTransportation::on_script_trigger_effect (ID 151)
RenaiTransportation/script/event/effect_triggered.lua:248: attempt to index field 'source_entity' (a nil value)
stack traceback:
RenaiTransportation/script/event/effect_triggered.lua:248: in function <RenaiTransportation/script/event/effect_triggered.lua:30>

Looks like that happens if you remove a thrower while its in the process of finding its target for overflow prevention purposes, the check only takes a fraction of a second so i guess you got unlucky lol. I added a check so it shouldn't crash in those cases for 0.8.3. Let me know how it goes

thanks
