Remove unused imports

You can do this in IntelliJ by pressing ctrl + option + O
Remove unused methods
Change isOwnedBy to isNotOwnedBy

You’re only using this to check that a resume is not owned by someone
so I changed the method so that it checks that.
Make method private
Change fields into local variables in their respective methods

No other methods are using them so there’s no need for them to be
fields.
Move printers only used for tests into test directory
Remove unnecessary <Job>
Rename methods from getSavedJobs/getAppliedJobs to printSavedJobs/printAppliedJobs
Merge changes

There were some existing compilation issues on
tzubeli/Object-Calisthenics. Those are still here.
Use isNotOwnedBy instead of isOwnedBy
