Wrong code completion in template if a list of generic objects is used

Assume the following code:
```
package test;

import java.util.ArrayList;
import java.util.List;
import java.util.Map.Entry;

public class OfByOne {
public static void main(String[] args) {
List> listOfEntryStrings = new ArrayList<>();
}
}
```

if one performs a foreach template it looks like this:
```
public static void main(String[] args) {
List> listOfEntryStrings = new ArrayList<>();
for (Entry entry : listOfEntryStrings) {

}
}
```
if one now cycles through to the `args` instead the result is the following invalid code (the type `String` has a extra `>` at the end):

```
public static void main(String[] args) {
List> listOfEntryStrings = new ArrayList<>();
for (String> string : args) {

}
}
```

Reproduce the foreach template completion with the shown List> example, then cycle to args and compare the generated loop variable type with the valid first result. Trace the template completion path responsible for selecting the iterated element type; done means cycling produces valid String syntax without the extra closing angle bracket.
