Avoid Crash when longpressing disabled predicted item

If a view does not handle its long press and return true, View.java calls getParent().showContextMenuForChild(this). However, in Hybrid hotseat case, predicted icons are removed from the hotseat when user long presses an icon. This will result in getParent() returning null.
