Subject: [PATCH] CTest: Clear custom vectors before populating (#12383)

Important when calling ctest commands in a loop from a script.
Each time Populate gets called, it uses the current definition
of the variable. Without the clear, it was accumulating additional
identical values each time through the loop.
