Fix some bugs and do some improvements

Fixed a bug related with resource paths.
Fixed the reset of the Results View, open shells will no longer be
closed, only when the view itself is closed. Therefor fixed concurrent
modification bug when shells were closed.

Improved refreshing of result items after deletion or creation of them.
Removed the warning of no connection to DS service if total number of
job ids is zero. Additionally the results node will be expanded after a
successful run after the new item has been added.
