1. `Dataset.dropDuplicates()` should definitely drop duplicates for all 
columns.

2. `Dataset.dropDuplicates(col: String)` should also drop duplicates for 
all columns matching the name.

My thoughts:

1. `Dataset.dropDuplicates()` should drop duplicates for all columns, the 
current implementation is wrong, this PR fixed it.
2. `Dataset.dropDuplicates(col: String)` should drop the first column 
matching the given name, or all matched columns? `Dataset.drop(col: String)` 
also drops all matched columns, the new behaviour seems reasonable. But we 
should be very careful, as this is a breaking change. cc @rxin
