Review Comment:
If we use
```
val namedExpressions = expressions.collect {
case e: NamedExpression => e
}
```
for the following query
```
EXECUTE IMMEDIATE 'SELECT :parm' USING parm;
```
we get the following column name
`variablereference(system.session.parm='Hello')` instead of just `parm`.
i.e. the output of `query.show()` prints:
```
+----------------------------------------------+
|variablereference(system.session.parm='Hello')|
+----------------------------------------------+
| Hello|
+----------------------------------------------+
```
