wallet.py: access unverified_tx with self.lock

Browse source 
Only actually needed due to Imported_Wallet.delete_address, but it takes some time to see this.
The verifier and the synchronizer both access unverified_tx but they are both run in the Network thread.
In any case, there does not seem to be a measurable performance hit when using the lock.
