Fixes issue #73

When running Robolectric tests we would get the following error:
`java.lang.IllegalAccessError: tried to access class kotlin.jvm.internal.DefaultConstructorMarker from class androidx.appcompat.widget.MaterialRecyclerViewPopupWindow$Companion`.

Additional changes:
- changed visibility of some internal classes i.e. `MaterialRecyclerViewPopupWindow` & `SectionedRecyclerViewAdapter` as they were not meant to be exposed anyway
- update Gradle & AGP versions
- target API version 28 -> 29
- moved `SanityTest` to `sharedTest` source set so that it can be tested with Robolectric as well
