Display transform on the SF traces

The transform flicker object doesn't have a "isNotEmpty" property
(return undefined) and was being ignored. Instead check if
object.isEmpty === true to allow objects without a isNotEmpty
property to be displayed

Bug: 176906864
Test: compile winscope, take a SF trace, check if the layers have a
trasnform property
