Support applying updated patches

If someone has updated an existing patch and pushed it, other team members will have this error after pulling and running `yarn install`:

`patch-package --reverse` will also fail because the patch has already been updated.
So every team member need to remove node_modules manually and to install packages again.
Wouldn't it be much more convenient to have fully transparent experience?
In such case patch-package could replace the previously patched package with the original one and apply new patch.
