Any ; at the end of if-else statement should be ignored

[LeeKaiXuan]

Description

When accidentally adding an extra semicolon (i.e., ;) at the end of the if-else statement, PSSGen will be traversed incorrectly and any previous action may be re-executed.

Scenario Code

component pss_top {
    action root_a {
        activity {
            do printStr with { str == "normal"; };
            if (1) {
                do print1;
            };
        }
    }

    action printStr {
        rand string str;
        exec body ASM = """printStr: {{str}}""";
    }

    action print1 {
        exec body ASM = """print1""";
    }

}

Expected Output or Behaviour

test.s.golden:

printStr: normal
print1

Error Message from PSSGen or JAVA

test.s:

printStr: normal
print1
printStr: normal

Error Message:

3d2
< printStr: normal
Test Result: FAIL
