Add check to not add a duplicate address entry with same offer ID and context.

Browse source 
In debugging trade protocol and taking same offer I could generate problems where the multisig entry was twice but with diff. keys, so take offer failed. I remember the error log to have seen in the past and I assume this was a rare bug we encountered when users took again the same offer which failed with an uncritical state earlier.
