Bug 1158403

Description of problem:
After migration to Uberfire to 0.5 the search feature in various perspectives works differently:

Before it worked (correctly) like this:
search in task list returned list of tasks
search in process definitions returned list of PDs
search in process instances returned list of PIs

Now it works like this: in whatever perspective you do the search, you will get a list of assets (as if when searching in Authoring perspective)

 
Version-Release number of selected component (if applicable):
kie-wb distribution war - build from 6.2.x tag for BPMS ER1

How reproducible:
Always

Steps to Reproduce:
1. Go to task list, create ad hoc task named "hiring"
2. in the search input at top right enter "hiring" and do the search

Actual results:
You will get list of assets containing "hiring" in their names, as if when searching in authoring perspective. Similar problem in other perspectives.

Expected results:
You should get task which contains the searched string in its name.
Similarly for Process instances / definitions.

Additional Info:
This functionality is also essential for UI tests where we use it to quickly access desired process definitions / instances by first performing search to avoid paging.
