table cache_shared already exists while upgrading

[mrjulfekar]

Hi when I try to update my Roundcube I faced this issue below

```
Updating database schema (2013052500)... [FAILED]
ERROR: Error in DDL upgrade 2013052500: [1] table cache_shared already exists
```
I am using the below command
```
bin/updatedb.sh --dir=SQL --package=roundcube --version=2019092900
```

Previously I was using Roundcube Version 1.4.11 and now I updated it to recent one.

One more I got in some DB's while updating.
```
ERROR: Error in DDL upgrade 2015111100: [19] FOREIGN KEY constraint failed

My Database Schema is something like this

I guess you have a message up db because if you were running version 1.4.11 that would have been way past version 2013052500 of the schema. you will probably have to fix it manually.
