[stable-2.18] Bugfix Delete Cached Nextcloud Client For Account Removal

[backportbot]

Backport of PR #1387

[alperozturk96]

continuous-integration/drone/pr / Failed due to / Failed to wait for server.

I saw the same error before. It's happening randomly.

This fails due to:
fatal: Remote branch artonge/feat/allow_metadata_update_for_subfolders not found in upstream origin

(https://drone.nextcloud.com/nextcloud/android-library/2872/1/2)

I fixed it already in stable-2.18 branch, so a rebase will help.
