Do not use @Autowired private variables

[TuxCoder]

Please do not use @Autowired on private variables.

This makes it more or less impossible to implement nice unit tests.
(At least from my experience with spring framework)

Use auto injection into the constructor, so in a unit test the constructor can given a dummy service and it is not needed to deal with changing private variables.

ref to unit tests: #3

If I'm wrong please provide an example unit test how to replace the injected bean.

edit: don't whant to refer to a user, so quoted @Autowired

Think also got fixed.

And for sure, to mention the autowired in CovidappApplication.java was not nessasary.

Haven't yet saw the this lombok framework yet, but does a good job.
Nice solution!
