Fix over-optimization that could result in an unsigned double field being
set to a negative value. (Bug #7700)
sql/field_conv.cc:
Don't treat real fields as identical when destination is unsigned and
the source is not.

Add test for setting double unsigned to a negative value from a signed double

Add test results
