fix(upload-list-adapter): invalid view holder adapter position

[alperozturk96]

Issue

1. UploadListAdapter using ThreadPoolExecutor, UploadGroup, GroupConfig, UploadGroupLoadRunnable to determine items of the list via complex and error prone way.
2. Refreshing list right away after async all causing sometimes

Exception in thread "main" java.lang.IndexOutOfBoundsException: Inconsistency detected. Invalid view holder adapter positionItemViewHolder{f9f6c09 position=7 id=-1, oldPos=-1, pLpos:-1 scrap [attachedScrap] tmpDetached no parent} com.owncloud.android.ui.EmptyRecyclerView{1c1ee0e VFED..... ......I. 0,0-1440,2596 #102000a android:id/list}, adapter:com.owncloud.android.ui.adapter.UploadListAdapter@ca641dc, layout:androidx.recyclerview.widget.GridLayoutManager@2eed02f, context:com.owncloud.android.ui.activity.UploadListActivity@8a5eb50

Changes

Just Section record used to get items for adapter.
Waits results of async calls before refresh adapter.
Use more suitable title for FINISHED type. Completed instead of Uploaded

blue-Light-Screenshot test failed, but no output was generated. Maybe a preliminary stage failed.
