KUrlNavigator: Block signals on toggleEditMode button during switchView
QAbstractButton::toggle is emitted in response to both user and programmatic changes, so us doing setChecked during switchView would also trigger the slot, applying the URL immediately, leading to spurious location changes.
In fe08d1ef it was explicitly changed to "toggled" for automated testing reasons, so an explicit QSignalBlocker is used instead.
Hit Ctrl+L in Dolphin, switched locations, hit Ctrl+L again, it would no longer switch to a random location.
