An additional semicolon (i.e., ;) at the end of do action should be ignored

[LeeKaiXuan]

Description

When accidentally adding an extra semicolon (i.e., ;) at the end of do action, PSSGen should ignore and execute the action only once time.

Scenario Code

component pss_top {
    action root_a {
        activity {
            do printStr with { str == "one ;"; };
            do printStr with { str == "two ;"; };;
            do printStr with { str == "three ;"; };;;
        }
    }

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

Expected Output or Behaviour

printStr: one ;
printStr: two ;
printStr: three ;

Error Message from PSSGen or JAVA

3d2
< printStr: two ;
5,6d3
< printStr: three ;
< printStr: one ;
Test Result: FAIL
