dbaccess: fix testCloneMovesPlusDeletions test
JunitTest_dbaccess_complex spuriously fails 1% of the time with:
1) testCloneMovesPlusDeletions(complex.dbaccess.RowSet)
java.lang.AssertionError: moving to the next record after |deleteRow| and
clone moves failed
at complex.dbaccess.RowSet.testCloneMovesPlusDeletions(RowSet.java:756)
The problem is that line RowSet.java:750 deleteRow() manages to delete
the last row in the set, because the positionRandom() is tricked to
position itself on the last row (which it tries not to do), becuase the
RowSet is currently positioned past-the-end on a deleted row and the
ORowSetBase::impl_getRowCount() is a lying bastard that adds 1 to the
result in this special case.
Funnily both the ORowSetBase::impl_getRowCount() and the test using
positionRandom() were added in CWS rowsetdel. Yay for randomized
tests!
