Clean tries to drop a table from an extension and fails

[svpace]

As instructed by @axelfontaine in #100 (comment)_

flyway version 5.2.4

V1__init.sql:

CREATE EXTENSION IF NOT EXISTS POSTGIS;

On clean:

ERROR: cannot drop table spatial_ref_sys because extension postgis requires it
         Hint:You can drop extension postgis instead.

Thanks for reporting. The extension dependency detection has now been extended to also include tables. Fixed.
