Updated findUnfollow function with selector

[andbas]

Looks like instagram changed unfollow button from span to svg element that broke "unfollow" automation, find a way to fix it with new selector without changing original logic.

hope this update will be merge soon ! it will be great to create a "loop" for this step and allow user to add his own document selector.... this will be "bypass" merge time
