Polishing
Ensure ServTEL doesn't reset ReqAttrs by accident

Prior to this commit, the ServletTestExecutionListener did not
overwrite RequestAttributes in the RequestContextHolder if the
ApplicationContext associated with the given TestContext was not a
WebApplicationContext; however, the ServletTestExecutionListener would
clear the RequestAttributes after every test method execution,
regardless of whether the context was a WebApplicationContext or not.
This behavior breaks backwards compatibility with integration tests
that managed the RequestAttributes in RequestContextHolder themselves.

This commit addresses this issue by introducing a TestContext attribute
named RESET_REQUEST_CONTEXT_HOLDER_ATTRIBUTE in
ServletTestExecutionListener. This attribute is used internally within
ServletTestExecutionListener to ensure that the RequestContextHolder is
only cleared (i.e., reset) if the ServletTestExecutionListener actually
populated the RequestContextHolder.
