Fix ecf-grpc console output on Karaf

[scottslewis]

On equinox, the current impl of togglereflection, addreflection, removereflection shows:

grpc://localhost:50002 |active

While on karaf these commands show

#6 (comment)

The output from equinox is correct, so the impl may have to be adjusted for Karaf usage of console.

It seems that his is likely a problem with the karaf console implementation, since it works correctly on gogo:

see https://issues.apache.org/jira/browse/KARAF-5750

I've fixed this in 1.4.2. Closing.
