Moving Bigtable TestColumnRangeFilter within unit test file.

[dhermes]

Doing this to match the order that the tested filters occur in row.py.

@tseaver Sorry this happened, I think it might've been caused by fly-by merges? I know you said the tests should come in the same order as the filters, which come in the same order as the fields in the proto spec.

To "verify" the order
