areNavigationStackEquals method

@visibleForTesting bool areNavigationStackEquals(Iterable<Destination> leftStack, Iterable<Destination> rightStack)

Check the equality between two list of destination.

leftStack to be verified. rightStack to be verified.

return true if both stack are equals.

Note: equals only in path not arguments or histories.
