Changing the abort identification unit test to depict fairly the behaviour of the innocent party. This commit removes lines from the unit test that changed the internal storage of round 1 and round 3 data (for the victim party). The culprit is identified in round 4 in this commit. The current change is only to the unit test. That is, there is no functional change to the protocol.

ecdsa/keygen: ensure paillier modulus == paillierModulusLen
...
In our implementation when generating safe primes, we also need the generated value to start with "11". So the factor of a paillier modulus >= 2^1023+2^1022. While (2^1023+2^1022)*(2^1023+2^1022)>2^2047, the result paillier modulus should be exactly 2048 bit.

Using make to reset certain variables after use, instead of setting to nil, considering that update may still be called. Adding a return function to the BaseUpdate, matching the master commit as of today. Without the function and the recursive call, the resharing unit test does not proceed after round 3.
