For honeynodes, even when maint-signal enable is set false, it is requiring a child object (testPattern) to be set.

However in for devices in lab it error-out saying that testPattern should be provided, only when the test-signal is true. YANG model "when" statement in the NE throws an error.

By distinguishing honeynode and other NEs, we can temporarily fix the problem, until we find the root-cause.
