Offer taken off offers list on invalid incoming take
A taker who sends an invalid take of an offer (for example, provided amount too low) will still cause the offer to be removed from the xmr maker's offer list, despite the take offer not being valid. Other peers will not be able to try to take the same offer since it is gone.

To reproduce:
- Create maker and taker1 and taker2
- maker creates an offer
- taker1 takes the offer but with provided amount too low
- taker2 tries to take the same offer, but it no longer exists
