[Rust] [DataFusion] Table API collect() should not require context

[asfimport]

The Table API requires the context to be passed into the collect() method which leads to this odd code.

let results = ctx.table("alltypes_plain")?
    .filter(col("c12").gt(&lit_f64(0.5)))?
    .aggregate(vec![col("c1")], vec![min(col("c12"))])?
    .collect(&mut ctx, 1024)?; 

Since the table comes from the context, it should not be necessary to pass the context back in.
