"undefined is not an object" when tour has ended

[pke]

https://github.com/xcarpentier/rn-tourguide/blob/72ae702217f311d5d5fbf0323e63022b383ba30b/src/components/Modal.tsx#L196

currentStep! is the culprit. It is undefined at that moment and should be better currentStep?.tooltipBottomOffset

The question is, why the code is executed after the tour has finished.
