Also update schema when clicking the Refresh button in Browse Data tab

When clicking the Refresh button in the Browse Data tab only the table
contents were refreshed, not the database schema. Hitting F5 however
updated both schema and data. This commit make sure the schema is
updated in both cases.

See issue #2325.
