fix(java): stop Show Usages waiting seconds on the configuration index after a change (#2011)

Usages counts clicked after a Java change waited for the configuration index to resolve every dependency's Spring metadata again (15–20 s in a Spring Boot project). The Java extension (1.8.0) now keeps each dependency JAR's metadata across rebuilds until the JAR or the classpath changes, and Show Usages shows the Java usages first, adding the configuration ones when the index takes longer.

Closes #1898
