Update keychains of ParseUser and ParseInstallation (#38)

* Update keychains of ParseUser and ParseInstallation during:

fetch, fetchAll, delete, deleteAll

* Drop codecov due to added code

* use carthage script to build using Xcode12

* Update ci.yml

* Add default callbackQueue to queries

* Gain back some codecov by adding more tests.

Cleaned up some code and comments

* Bump codecov

* Add test case for delete ParseUser.

* Reduce to return try

* Fix some spacing
