Enable pull-to-refresh in upload/document share intent

[shtrom]

Actual behaviour

• Pull-to-refresh when browsing in the upload/share intent does nothing

Expected behaviour

• Pull-to-refresh when browsing in the upload/share intent should refresh the view and show new folders

Steps to reproduce

1. Share a document from another app to Nextcloud
2. Go to any folder
3. From another device, create a new sub-folder to that folder
4. On the first device, pull-to-refresh

GitMate.io thinks possibly related issues are #2443 (Improve uploading/sharing options), #2575 (Enable "Upload option" when uploading files using share function outside the app), #2691 (Instant Upload not syncing after re-enabling it), #569 (Unable to refresh), and #1089 (Sharing with "password rule" enabled is not working).

Doesn't seem like any of those issues are related. Thanks @nextcloud-android-bot

We refresh when entering a folder, this should be good enough.
