Make MIExpressionsTest.testUpdateOfPointer use SyncUtil
Modify MIExpressionsTest.testUpdateOfPointer so that it only uses synchronous methods. There is no change of behavior intended, the test should do pretty much the same thing as before, but should be a bit more readable. One difference is that we don't need to re-create the IExpressionDMContext objects when we want to re-evaluate the expressions (after stepping the 2nd time). We can just call getExpressionValue on the again, which will trigger a -var-update. Change-Id: I09bb914b097888bf3146df0096eb9d824441ffa8 Signed-off-by: Simon Marchi <simon.marchi@polymtl.ca>
