Roundcube plugin 2.0.2 failure to upgrade

Recently i upgraded to i-MSCP 1.5.3 from 1.5.1.
I was using roundcube 2.0.1 plugin.
I did not deleted the plugins before upgrade.
After upgrade plugin was not working because of the wrong directory bug.
I downloaded roundcube 2.0.2 plugin. Erased in mysql the id of roundcube and uploaded
new version.
I have the following error:

Plugin installation has failed: SQLSTATE[42S21]: Column already exists: 1060 Duplicate column name 'instance'Seems i have to drop other tables ? Can anyone help a little ?

Ok i found solution.
Here it is.
First you must erase from mysql table plugins the id of roundcubeplugin.
Then upload older version 2.0.1 of roundcubeplugins.
Now you must fix this bug:
Edit the /var/www/imscp/gui/plugins/RoundcubePlugins/backend/RoundcubePlugins.pm file and change line 665:
from: ."/var/local/imscp/composer.phar require --no-ansi -n -d=$webmailDir --update-no-dev "
to: ."/var/local/imscp/composer.phar require --no-ansi -n -d $webmailDir --update-no-dev "
Now from webpane force retry. Install will go on and when it finish you must deinstall the plugin then delete.
You can now upload the latest version 2.0.2 and everything is ok.
The idea was to keep all contacts and everything.
I hope i am doing it ok

Yes I know manually is very bad.

The problem is that everything to be OK you must disable/uninstall all plugins. Then you make upgrade and reinstall plugins. This takes a lot of time.

My suggestion is if you can automate this somehow in the future.
