Subject: [PATCH] fix(ios): cast to `CDVFile` when getting the plugin by
 `getCommandInstance` (#385)

- `CDVCommandDelegate getCommandInstance` returns a `CDVPlugin` which does not know about the selectors of an inherited class like `CDVFile`. If not casted, XCode will throw an error like `error: no visible @interface for 'CDVPlugin' declares the selector 'filesystemForURL:'`.

If so, normalize it by removing empty path segments, and check with File to see if any of the installed filesystems will handle it. If so, then we will end up with a filesystem url to use for the remainder of this operation.
