OPP: Remove try again button for failed transfer

The resent task will fail due to SecurityException if
the Bluetooth app doesn't have permission to access the URI.
In normal case, the Bluetooth app only gets temporary
permission to read the URI from another app. The user
should use the same app to retry failed outbound transfer
to get temporary permission again.
