CppunitTest_sw_uiwriter: avoid SfxLokHelper

It assumes that the process has only a single document opened
(createView() creates a new window on the frame returned by
SfxViewFrame::First()), while it's possible that in this test an other
testcase forgot to dispose its component.

This way testCursorWindows() depends less on other testcases, and
ideally all testcases should be entirely independent of each other.
