PB-1204: fix unrelated test failure on import KML

don't know why this pops up on this PR which doesn't change anything in the import KML, but I've added the necessary intercepts on the search made while importing a KML to fix the flakyness of this test.
Was certainly due to some race condition on the real search service responding faster than expected, we should not use the real service for such tests anyway...
