removing folder from image collection does not update folder list
1) Import some folders (recursively)
2) Select 'folders' from 'collect images'
2) Right-click single folder and 'remove...'
Expected result: Folder disappears, list gets updated and you can remove more folders.
Real result: Folder does not disappear from the list and right click gets disabled so that you cannot remove anything anymore. If you change from 'folders' to e.g. 'tag' and then back to 'folders' the removed folder has disappeared and you can remove folders again.
Tested: darktable 2.2.2 on Ubuntu 16.04
