Remove the useless node :

<DbProviderFactories>
  <add name="MySQL Data Provider" invariant="MySql.Data.MySqlClient" description="MySQL Database Provider" type="MySql.Data.MySqlClient.MySqlClientFactory, MySql.Data" />
</DbProviderFactories>

And specify version of your MySqlClient provider like :

<provider invariantName="MySql.Data.MySqlClient" type="MySql.Data.MySqlClient.MySqlProviderServices, MySql.Data.Entity.EF6, Version=6.10.4.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d"></provider>
