Fix NSMountLogic in case when user has no running applications

In some cases directory /run/user/UID/ may exist, but /run/user/UID/apps/
might not. Such case was incorrectly handled in NSMountLogic::readFiles(),
it caused an exception to be thrown.

Fixed implementation first checks whether directory exists before trying
to read it.
