Fix 11-year-old mis-categorized error code in OP_IF evaluation
This was introduced by commit ab9edbd. It appears the original author may have gotten tired and pasted the wrong error code into this 1 place. Every other situation where the value stack lacks the required number of arguments for the op-code, SCRIPT_ERR_INVALID_STACK_OPERATION is reported. Not so here. This commit fixes the situation. Also in this commit: - Fix script_tests to adjust to the corrected error message - Fix p2p_invalid_tx functional test to produce the desired error message
