Run jep test at INFO level, not DEBUG

The DEBUG level is too granular for normal use. In particular, the
message "The JVM is already running" appears many times when running in
debug mode. We could change that message to print only in JPYPE mode,
but I think INFO is a better fit for CI generally anyway.
