Fix column test matching when using quotes in BigQuery (#122)

I noticed the following issue in BigQuery, when using models where a
column has "quote: true" defined.
In that case the data_tests defined for that column were not matched to
that node.
Consequently the test has_uniqueness_test failed.

When looking into the dbt manifest I saw that in the test node at
test_metadata.kwargs.column_name the name contained the quotes (with
grave accent `), e.g.
```
"column_name": "`my_column`"
```
However at the model node it is always without the quotes, e.g.
```
"columns": {
  "my_column": {
    "name": "my_column"
```
