rpc/gui: Remove 'Unknown block versions being mined' warning

Due to miners inserting garbage into the version numbers, the current
version signalling has become completely useless. This removes the
"unknown block versions" warning which has the tendency to scare
users unnecessarily (and might get them to "update" to something
bad).

It preserves the warning in the logs. Whether this is desirable can
be a point of discussion.
