Rename Spr3896SuiteTests to Spr3896TestSuite

This commit renames Spr3896SuiteTests to comply with our naming
convention for test classes that should be executed via the Gradle
build.

The effect of this commit is that test classes included in that "suite"
are no longer executed twice in the build. Consequently, Gradle and
Bamboo will now report the same number of executed tests for the
spring-test project.

spring-test/src/test/java/org/springframework/test/context/junit4/spr3896/Spr3896SuiteTests.java → spring-test/src/test/java/org/springframework/test/context/junit4/spr3896/Spr3896TestSuite.java
