[HBASE-9114] Fix TestChangingEncoding

Author: manukranthk

Summary: TestChangingEncoding tries to do alterTable when the table is disabled. The region reopener is not activated if the table is disabled, which seems unintuitive. So, removing the check to fix this test.

Test Plan: Run mrunit and check the failed tests locally
