listTables method doesn't pass table labels

[tloszabno]

Hello,

I noticed that java-bigquery library does not pass-through labels from the rest API list table method. We need to read labels in our project, without that we need to fetch details for each table, which causes many problems, while all required data is available but just not converted.

The problem I debugged is in the method listTablesSkipExceptionTranslation where there is no conversion of labels.

Look at the breakpoint in the debug mode:

I will attach Pull Request to add labels.
