Added the biotype table to the list of "global" tables

Created by: muffato

Description

Add the biotype table to the test core databases.

Use case

The script currently doesn't copy the biotype table, meaning that the Core API will silently return no group for all genes of the test database.

Benefits

Biotype groups will be retrievable

Possible Drawbacks

Slightly larger test databases (16 KB according to SHOW TABLE STATUS)

Testing

Have you added/modified unit tests to test the changes?

No, the script doesn't have any unit tests.

If so, do the tests pass/fail?

Have you run the entire test suite and no regression was detected?

Yes
