Fixed when FishBun.isStartInAllView(true) returned empty array to onActivityResult

[LGFox]

Steps to reproduce:

1. In WithActivityActivity.kt:147 add .isStartInAllView(true)
2. Run demo project and select Activity in StartActivityForResult(LIGHT)
3. Select a photo and press CHOOSE

Expected result: a photo being selected
Actual result: app crashes because path at WithActivityActivity.kt:60 is null

What changed:

1. Call finish() instead of pickerView.finishActivity() which correctly supports isStartInAllView(true)
2. Refactored: used pickerRepository.checkForFinish() everywhere
3. Removed extra .setIsUseAllDoneButton(true) in demo project

Hi @sangcomz, could you please check this PR and merge it? It's relatively small and straight forward. I was actually going to submit basically the same changes but now I saw that LGFox already did the work.
Thank you for this library and your work on it.
