SUMMARY
The contentItem of a SwipeListItem will now reach to the right end of the SwipeListItem, instead of correctly leaving the spaces at the right for its actions. This is a regression though I do not know in which version it was introduced exactly. It was introduced more than two months ago.

Also, if the bug is in QQC2-style-desktop instead of Kirigami, please reassign accordingly.

STEPS TO REPRODUCE
1. Given this code:
```
    ListView {
      anchors.fill: parent
      model: 3
      delegate: Kirigami.SwipeListItem {
          contentItem: RowLayout {
            Label {
              text: 'aaaaa'
              Layout.fillWidth: true
            }
            Rectangle {
              color: 'green'
              Layout.preferredWidth: 10
              Layout.preferredHeight: 10
            }
          }
          actions: [Kirigami.Action {
            icon.name: 'document-edit-symbolic'
            text: 'test'
          }]
        }
    }
```
2. Run it

OBSERVED RESULT
The green square is at the right end of the SwipeListItem and overlaps with the actions

EXPECTED RESULT
The green square should be on the left of the actions
