Subject: [PATCH] lottie/text: Fix incorrect text range without end condition

Improving text render compatibility by fixing wrong Text Range.

When lottie doesn't have `end` prop in the range, system must ignore condition regarding to `end`.

The original logic unintentionally swaps `start` and `end` prop, because `end` is the zero in this case. Then the text range animation behaves the opposite.
