phaseEnded/stepEnded don't occur when navigation is skipped and fadeStepWhenSkipped is disabled

**Dependencies**: `navigationSkip: true`, `fadeStepWhenSkipped: false`, `preventReverseSkipping: false`

**Problem**: With the above dependencies, when the user navigates between steps quickly, the `phaseEnded()` and `stepEnded()` do not occur until navigation skipping has stopped. This may cause issues for themes that change the states/styles of steps based on these public events. For example, when a step ends, it's background colour is changed. Without these events, the background won't be able to change when navigation skipping occurs.
