Steps to reproduce the issue

• Uninstall NewsFeeds & Banners from Joomla 3.4.6

• Visit Extension -> Manage -> Database and you got an error that the database isn´t up to date. The following DBs do have problems:

  Table 'test_newsfeeds' should not have column 'filename'. (From file 3.0.0.sql.)
  Table 'test_newsfeeds' does not have column 'description'. (From file 3.0.0.sql.)
  Table 'test_newsfeeds' does not have column 'version'. (From file 3.0.0.sql.)
  Table 'test_newsfeeds' does not have column 'hits'. (From file 3.0.0.sql.)
  Table 'test_newsfeeds' does not have column 'images'. (From file 3.0.0.sql.)
  Table 'test_banners' does not have column 'created_by'. (From file 3.0.0.sql.)
  Table 'test_banners' does not have column 'created_by_alias'. (From file 3.0.0.sql.)
  Table 'test_banners' does not have column 'modified'. (From file 3.0.0.sql.)
  Table 'test_banners' does not have column 'modified_by'. (From file 3.0.0.sql.)
  Table 'test_banners' does not have column 'version'. (From file 3.0.0.sql.)

Additional to that the following errors will be shown:
