[TASK] Install tool fails if LocalConfiguration EXT/extConf does not exist

On fresh instances, the install tool may fail if path EXT/extConf
which is written as b/w compat layer does not exist, yet.
Patch catches the (generic) exception from ArrayUtility->getValueByPath()
and initializes the value to an empty array to continue in this case.
