Support Spring autowire two and more different beans of one type

[tepa46]

Description

Fixes #2389

Now Spring unit tests can autowire two different beans of one type.

If all test executions use only one autowired bean of some class, then we can mock this variable by @mock annotation,
else we need to use simple mock.

How to test

Manual tests

Manually tested on a spring-boot-testing project and a project that does not use Spring framework.
