[Security Solution][Detection Engine] add tests for saved query shared in multiple spaces

[vitaliidm]

After introducing sharable saved queries in #163436, we need to add functional tests on our side, to ensure functionality works as expected and there no gaps in coverage.

Possible scenarios:

1. create rule and execute rule with shared saved query from another space
2. edit rule and execute it with shared saved query from another space
3. delete saved query from another space, check expected error on execution
   4.export/ import rule with shared saved query into original rule space and space from where saved query originated
