Don't let testSpreadsheetViewSettingsProperties interfere with existing tests

...by giving each test its own mxComponent.

At least my Windows builds started to fail CppunitTest_sc_tabviewobj with

> C:/lo/core/test/source/sheet/xviewsplitable.cxx:36:sc_apitest::ScTabViewObj::testSplit
> equality assertion failed
> - Expected: 1
> - Actual  : 0
> - Wrong column

after 95307f2ca73480176634e5cc46d96a19b735e87b "tdf#45904 Move
_SpreadsheetViewSettings Java tests to C++" added the call to
testSpreadsheetViewSettingsProperties ahead of the call to testSplit.  (And
allowing multiple tests to work on shared state and interfere like they
apparently do here seems rather brittle in general.)
