CIF PLC code generator generates escaped candidate names
`CifToPlcTrans.getPlcName` contains:
```
String candidate = getAbsName(obj).replace('.', '_');
```
This generates candidate names based on escaped absolute names of CIF objects. It should be:
```
String candidate = getAbsName(obj, false).replace('.', '_');
```
This avoid escaping and thus `$` characters in the candidate names.
We should add a test for this as well.
