0029247: Tests, CheckCommands.tcl - Tcl exception "expected integer but got 3dviewer...

Test cases on macOS (using native tcl from /usr/lib) fail when $lst starts with numeral, because upvar guesses that its first parameter is level rather than otherVar.
The fix is to explicitly supply level to 1 (default value if uplevel is omitted) to avoid tcl exception "expected integer but got 3dviewer".
