[SQLLab] Timestamp column type metadata shows up incorrectly in left panel

[michellethomas]

If you look up a table in sqllab on the left hand side to see the table metadata, tables with timestamp types show up as:

<class 'superset.models.sql_types.base.literal_dttm_type_factory..TemporalWrapperType'>

Expected results

The correct type.

Actual results

<class 'superset.models.sql_types.base.literal_dttm_type_factory..TemporalWrapperType'>

How to reproduce the bug

1. Add schema and a table to the left panel for a table with a timestamp type to see the table metadata (we noticed this in Presto)
2. When the table metadata shows up see "<class 'superset.models.sql_types.base.literal_dttm_type_factory..TemporalWrapperType'>" for the type instead of the correct type

Left panel

Environment

(please complete the following information):

• superset version: master
