Seth Howell 190b2245c5 test: make xtrace_disable multi-call safe.
Previously, if you made two sequential calls to xtrace_disable without
calling xtrace_enable, you would lose the original value of x. Now this
is not the case. It allows us to call xtrace_disable freely without
worrying about whether xtrace_disable is invoked later in a function we
call.
