This was added in commit 600987b4
(tdf#45904 Move remaining _XCellRangeReferrer Java tests to C++,
2018-06-13), but as it was reported it fails on some Linux and Windows
machines.

Disable it till it's clear why that happens, as discussed at
<https://lists.freedesktop.org/archives/libreoffice/2018-July/080521.html>.

For the record, the failure what I can see is like this:

	xcellrangereferrer.cxx:32:Assertion
	Test name: sc_apitest::ScTabViewObj::testGetReferredCells
	equality assertion failed
	- Expected: Sheet: 0 StartColumn: 0 StartRow: 0 EndColumn: 6 EndRow: 22
	- Actual  : Sheet: 0 StartColumn: 0 StartRow: 0 EndColumn: 6 EndRow: 23

	Failures !!!
	Run: 6   Failure total: 1   Failures: 1   Errors: 0
