Update ACAccountStore+Promise.swift

replaced String by AnyObject 
from ACAccountStore
```swift
    // Obtains permission, if necessary, from the user to access protected properties, and utilize accounts
    // of a particular type in protected operations, for example OAuth signing. The completion handler for 
    // this method is called on an arbitrary queue.
    // Certain account types (such as Facebook) require an options dictionary. A list of the required keys
    // appears in ACAccountType.h. This method will throw an NSInvalidArgumentException if the options
    // dictionary is not provided for such account types. Conversely, if the account type does not require
    // an options dictionary, the options parameter must be nil.
    func requestAccessToAccountsWithType(accountType: ACAccountType!, options: [NSObject : AnyObject]!, completion: ACAccountStoreRequestAccessCompletionHandler!)
