Check if options are available before matching on them

This prevents a QML warning when the ListModel is created before the property provider is. This QML warning looked like this:
2020-03-20 15:04:30,012 - WARNING - [MainThread] UM.Qt.QtApplication.__onQmlWarning [406]: file:///home/trin/Gedeeld/Projects/Cura/cura/../resources/qml/MachineSettings/ComboBoxWithOptions.qml:74: TypeError: Cannot call method 'match' of undefined

Done during Turbo Testing and Tooling.
