Set ClipData with attachments URIs on bugreport notification.

The ACTION_SEND_MULTIPLE contract expects the EXTRA_TEXT to be an
ArrayList<String>, but it's currently set as String, which causes an
exception when exporting the EXTRA_STREAM as ClipData.

The right approach would be changing the EXTRA_TEXT content, but that
would break some clients like GMail, so a safer fix is to explicitly
set the ClipData.

Also removed unused variables and imports.
