wallet: Check last block and conflict height are valid in MarkConflicted

Browse Source 
MarkConflicted calculates conflict confirmations incorrectly when both
the last block processed height and the conflicting height are negative
(i.e. uninitialized). If either are negative, we should not be marking
conflicts and should exit early.
