Subject: Fixed state of screen-reader wher screen-reader exits abnormally
X-Git-Tag: accepted/tizen/common/20160203.160738~10

Fixed state of screen-reader wher screen-reader exits abnormally

When screen-reader e.g. crashed, bus-launcher didn't check if the process
is still running before it tried to terminated it. In result screen-reader's
invalid PID was kept and new screen-reader couldn't be launched.
