Bug fix: Correctly save objectId of Installation

[cbaker6]

ParseInstallation is slightly different than other ParseObjects as it's created with a unique identifier (installationId) locally on the device and may or may not be saved depending on the app use case. This fixes a bug for when the Installation is saved to the server and the objectId of the Installation wasn't saved to the Keychain. This prevents the ability to fetch an updated Installation because fetch is based on the objectId.

Fix #115 Should also fix multiple save issue mentioned in #93

• Use installationId's when comparing objectIds to update the keychain
• Update testcases
• Fixed bugs with deleteAll for ParseInstallation and ParseUser
• Added changelog entry
