Change condition for MeterRegistry from class to bean

[sebastiankirsch]

Fixes #497

[Nephery]

Thanks for raising this PR!

Looks like a test is failing though. Can you try changing the annotations (lines 10-11) to this?

@AutoConfiguration(after = { MetricsAutoConfiguration.class, CompositeMeterRegistryAutoConfiguration.class })
@ConditionalOnClass(MeterRegistry.class)
@ConditionalOnBean(MeterRegistry.class)

This is the pattern used in a lot of meter autoconfiguration classes such as https://github.com/spring-projects/spring-boot/blob/v4.1.0/module/spring-boot-micrometer-metrics/src/main/java/org/springframework/boot/micrometer/metrics/autoconfigure/jvm/JvmMetricsAutoConfiguration.java#L59-L61

Got it.
Using no IDE, hope this works 🤞

Well this was failing; I guess that won't go away by the changes.

Can you try removing @Configuration(proxyBeanMethods = false)? I think it might be conflicting with @AutoConfiguration
