User visibility filter should log the key on parse exception

[keith-turner]

The following code should log the key in addition to the exception because that would make it much easier to find the offending data.

accumulo/core/src/main/java/org/apache/accumulo/core/iterators/user/VisibilityFilter.java

Line 114 in 98549b6

log.error("Parse Error", e);

The system iterator for visibility filtering does log the key.

accumulo/core/src/main/java/org/apache/accumulo/core/iteratorsImpl/system/VisibilityFilter.java

Line 90 in 98549b6

log.error("BadArgumentException with visibility of Key: {}", k, e);
