Can't reinstall wallabag with pdo_driver <> sqlite and db path filled

[nicosomb]

Issue details

Because I switched from sqlite to mysql database on localhost, I discovered a bug (not a critical one, I know).

Environment

• wallabag version (or git revision) that exhibits the issue: master
• How did you install wallabag? git clone
• Last wallabag version that did not exhibit the issue (if applicable):
• php version: 7.2
• OS: macos
• type of hosting (shared or dedicated): localhost
• which storage system you choose at install (SQLite, MySQL/MariaDB or PostgreSQL): so many 😄

Steps to reproduce/test case

• install wallabag with pdo driver : mysql
• fill the database path (like for sqlite installation)
• try to reinstall wallabag (bin/console wallabag:install)
• you'll have:

I think it's more an "issue" on Doctrine than on wallabag.
