fix(tests): refactor tests and junit platform name to execute startup…

… tests

Startup test under module keiko-mem-spring and keiko-redis-spring are not executing and throwing below error:

```
> Task :keiko-mem-spring:test FAILED

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':keiko-mem-spring:test'.
> No tests found for given includes: [com.netflix.spinnaker.q.mem.spring.SpringStartupTests](--tests filter)

```

```
> Task :keiko-redis-spring:test FAILED

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':keiko-redis-spring:test'.
> No tests found for given includes: [com.netflix.spinnaker.q.redis.spring.SpringStartupTests](--tests filter)

```
After fixing these issues by refactoring the junit platform as `junit-jupiter`, encountered below errors while execution:
```
Failed to load ApplicationContext

```
Failed to load ApplicationContext
Caused by: org.springframework.beans.BeanInstantiationException: Failed to instantiate [com.netflix.spinnaker.q.redis.RedisQueue]: Factory method 'queue' threw exception; nested exception is redis.clients.jedis.exceptions.JedisConnectionException: Could not get a resource from the pool

```
To fix these errors refactored the test by adding `Registry` and `JedisPool` beans.
