Fixes deadlock on resume data saving during transport switch

Issue was happening due to
- resume data restoring thread was acquiring app subscription lock and
  then application list lock
- transport switching thread was acquiring application lock and was
  saving resume data and trying to get subscription lock

Now after filtering switching application from application list its lock
will be released
