Description

Before a DB connection is established, executing a command such as typeinfo and nativesql results an NPE shown at the console:

beeline> !typeinfo
java.lang.NullPointerException
beeline> !nativesql
java.lang.NullPointerException

Instead, a message, such as "No current connection" should be given, as in case of some other commands, such as dropall.
