[TECHNICAL] Resource leak in `CopyAndUploadContentUrisTask.java`

[dataCenter430]

File: owncloudApp/src/main/java/com/owncloud/android/ui/asynctasks/CopyAndUploadContentUrisTask.java
In the loop over URIs (lines 147–182), inputStream and outputStream are reassigned every iteration but never closed inside the loop.
Only the last iteration’s streams are closed in finally.
All previous streams are leaked.
Fix: Close each stream after use in the loop (e.g. in a finally block per iteration, or use try-with-resources), then set to null before the next iteration.
