Return after returning player offers to avoid redundant remove offer following (!237)

#### Summary

> Should fix [Issue 523](https://dev.sp-tarkov.com/SPT-AKI/Issues/issues/523)

Tested a few different scenarios and the items were always correctly removed and returned to the player, however I did see the console warnings reported in the issue.

Both of the following call `this.ragfairOfferHandler.removeOffer(...)`:

 - `this.returnPlayerOffer(...)`
 - `this.removeOfferById(...)`

The latter logs a warning to the console because the offer is already removed when we reach that point.

This fix simply returns after the offer has been returned to the player, letting `returnPlayerOffer` deal with removing from the flea
