Test Bean Overrides do not honor `@Primary` semantics

[sbrannen]

Overview

Spring Boot has honored @Primary for @MockBean and @SpyBean since Spring Boot 1.4.3; however, the support for @Primary was lost when the @MockBean/@SpyBean support was ported from Spring Boot to Spring Framework's new Bean Overrides feature in the TestContext framework.

Since the lack of this support constitutes a regression for anyone migrating from @MockBean/@SpyBean to @MockitoBean/@MockitoSpyBean, I have labeled this issue as a "bug".
